After saving segment with a custom name to a preset a preset cannot be saved with the default segment name to show time using scrolling text.

[eoncire]

What happened?

I have a 16x16 2d matrix set up which I am using to display text. I created a preset with a named segment "Hello" to display that text when the preset is loaded. I created another preset after I blanked / reset the segment name hoping to have a preset to return to the time display. It appears that when the preset is saved with a blank segment name there is no "n" value in the preset JSON. I have tried to modify the preset JSON before saving to add a "blank" "n" value but it did not work.

To Reproduce Bug

Using a 2d matrix and the "Scrolling Text" effect;

1. Give the primary (only) segment a name of "Hello" and click the check box to apply.
   a. The matrix displays "Hello"
2. Create a new preset in Error Compiling #1 and save.
3. Erase / blank the segment name and click the check box to apply.
   b. The matrix displays the time / date
4. Create a new preset in ESP32 support & flickering #2 and save.
5. Load preset Error Compiling #1 and the matrix shows the text "Hello"
6. Load preset ESP32 support & flickering #2 and nothing changes.

Expected Behavior

When loading preset #2 in the above example the time / date should be shown.

Please post preset content.

Please post preset content.

This is the preset content with the "blank" segment name which should show the time. If i load a preset with a segment named "Hello" it will display "Hello" on the matrix. If I select the below preset after nothing will change.

{"on":true,"bri":255,"transition":7,"mainseg":0,"seg":[{"id":0,"start":0,"stop":16,"startY":0,"stopY":16,"grp":1,"spc":0,"of":0,"on":true,"frz":false,"bri":255,"cct":127,"set":0,"col":[[8,255,0],[0,0,255],[8,255,0]],"fx":122,"sx":255,"ix":128,"pal":2,"c1":0,"c2":162,"c3":16,"sel":true,"rev":false,"mi":false,"rY":false,"mY":false,"tp":false,"o1":false,"o2":false,"o3":false,"si":0,"m12":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0},{"stop":0}]}

Add "n":"" into "seg":[{...}] section.
Name may not be added to conserve RAM during processing.

Add "n":"" into "seg":[{...}] section. Name may not be added to conserve RAM during processing.

I added that to the JSON then clicked save, but it doesn't save after the page refreshes.

What i put in.

What is there after clicking save.

[eoncire]

Add "n":"" into "seg":[{...}] section. Name may not be added to conserve RAM during processing.

If I put some other text in the double quotes it will save that and display the text, but it doesn't seem to like having just the double quotes / blank.

Didn't mean to close this issue, clicked the wrong button...

Note: when saving preset, if "Save bounds" is unchecked, segment names are not saved.

Noted. I had "Save Bounds" checked by default when saving these presets. It looks like if the segment name is set to the default it also does NOT save the name.
