Hello! I’ve been experiencing a problem when customizing card templates. 1. I’ve installed this add-on: [1087328706](https://ankiweb.net/shared/info/1087328706) (for the sake of completeness: I use two add-ons, the second being [1463041493](https://ankiweb.net/shared/info/1463041493) 2. I’d used the windows program 3. It had worked some time (1 day?), in both windows and android. Those are the two versions I use and where I synchronize everything 4. By uploading (I believe once it did happen in windows, once on android) I had become a message, that my decks are incompatible and have to be overwritten, which I confirmed 5. Since then the changes haven’t been there anymore and the default template is back - I made this again and it happened again (as I said, once I got the incompatibility in windows, once on android) - I’ve made it again and this time I haven’t got an incompatibility message so far, my customizations have been nevertheless deleted, I believe like: WIN - changes made (OK), Android sync multiple times (OK), WIN sync - NOT OK. Is there anything I’ve been doing wrong? thanks ---

When you want to make unmergeable changes like modifying fields, you should: 1. Sync all your devices. 2. Make the changes on device A. 3. Sync device A, choosing “Upload to Ankiweb”. 4. Sync all other devices, choosing “Download from Ankiweb”. ---

thanks! But - is modifying a `Styling` an umergeable change? I’m not asked to merge after making such a change. Only in a day or so - very randomly and suddenly… ---

No, it’s not. Maybe an add-on is doing some stuff behind the scenes? Anki tries to warn you before you make unmergeable changes. ---

that’s my guess too - is there any good way to check this? I’ve already been trying to check this: I’ve disabled the [1087328706](https://ankiweb.net/shared/info/1087328706) add-on after I posted the first message here add-on and been waiting whether it happens again or not. ---

If it was a once-off occurrence, it was probably caused by [Full sync required without comprehensible reason](https://forums.ankiweb.net/t/full-sync-required-without-comprehensible-reason/15348) ---

OK, thanks. I’m gonna keep the add-on turned-off for a few days anyway and then I’ll turn it on again to be 100% sure. ---
