Replace Spells/reset Interface?

Sers

Now I have a more extensive proplem on my 2nd account.  I removed all the spells from the bar to rearrange them. but the spells can't be dragged into the bar Oo

i also thought it would help me fix this bug that came up in the last fight

see screen

https://ibb.co/zmtj0bhis there any way I can reset the interface?

Edit after a restart of the app, everything works
