Using DIg-Quad-ESP32, WLED 13.1, WIFI connection, and Firefox. Laptop and ESP32 separated by about 6 feet. I have about 20 presets. All presets display as expected when selected in WLED.
Used WLED->Config to create a backup of my presets. Noticed that presets.json has some sections containing 20-30 spaces when viewed with an editor or online json formatter.. Also noticed the presets where the spaces occur are incomplete. Made a second preset.json backup and the two files have no differences.
Have not tried to load the presets.json file into WLED over concern of preset corruption as reported in another thread. Backup cfg.json looks ok.
I am currently unable to attach the presets.json file due to my new user status.
EDIT: Appologies. After a more thorough examination of the file, all preset data is present and accurate. The extra spaces has just caused the data to be reordered a bit. Assume the extra space data will be ignored when the the file is used in a restore operation.
