Hello @Josh,
To dig deeper, we might review again similar cases you treated here before, e.g. Search results for 'Start tag expected, '<' not found' - KoboToolbox Community Forum
All since March, mostly June this year… Modal edit, preview …
So, all cases popped up after March release?
Release Notes - version 2.022.08, 2.022.08a
(I couldn’t find a similar error before or in the ODK forum.)
For me, it seems related to #3751… Your “solutiion” with download/upload indicates that some difference against direcly editing makes the turn.
Sorry, from a user regard, it is confusing and a bit strange that different (parsing/converting) tools are working in the background and create such problems, esp. after an update.
