Possible bug: keep losing "read" chapter marks.

[omnilynx]

I rely on the marks for chapters I've read (the eye icons). Occasionally, a manga I've read will lose all its marks. It doesn't happen regularly, and I don't know how to trigger it, but it's often enough that I'm sure it's not just my imagination or a one-time quirk.

I'm having the same problem. Came here to create a topic about it, though you've beaten me to it.
So you're not the only one. I hope this gets fixed soon.

It happens if you change the follow type to something other than Reading.

I have this issues aswell, just recently. On some I have on read follow, some of the marks are gone, not all but some. Also completely gone on a couple of others. and have not changed anything.
