No arrow and addonskin window too big

Hello, I have 2 problems with the Elvui chat.

I used the search function here before and found 1 same problem, but that is from July.
And according to Curse, Addonskins is also updated to patch 8.3.0.

To my problems:
When I embed details in the chat, the details window is larger than the Elvui chat. Can this be fixed?

Problem 2: I can't go back to details. In the past there was always a small arrow under the chat to switch to details after the fight. But this arrow is gone now. Has the button / arrow been removed? See before after picture. And yes, my information bars are active!

Should you still switch to the alpha version anyway?
