<$tags> appearing in iOS

Hello,

Been using Scrivener on macOS & iOS for a while, with no major issues. Today I started seeing the following string preceding the text of a certain style on iOS:

<$ScrKeepWithNextSplittable>

This is visible both on the iPhone and on the iPad and is very annoying because I don’t know if I can edit the files on the iOS devices. If I change a bit of text outside of the tag and sync back, the text appear normally on macOS (the tag is never visible).

Please fix or otherwise explain how to get this back to normal behavior again. I have done nothing I can think of to modify how the apps interact (no OS upgrades or anything).

Thanks.

Confirmed as bug by L&L.
