Can't edit individual tags?

After recent updates, I can no longer select individual tags when editing a chapter, nor can I insert tags in between other existing tags. Basically, the cursor can't be moved from the end of the list.

Is there a way I can fix this, or will it require the site moderators to change/revert something first?

Actually, the most recent time I went to check, I couldn't see any of the tags on the chapter I was trying to edit...

 

It is possible to delete tags. (Click on them to highlight them, and then delete with Delete or Backspace.)

Inserting tags in between or moving them doesn't seem to be possible as of now.

 

Don't suppose you have any idea if this feature is planned to be added back at some point?

 

So follow up here, the tags I've tried to add since this update are not showing up, even multiple days later. They are there when I go to edit the tags, but cannot be seen on either of my devices when viewing the story or individual chapters.
