I've been using Layerslider for a while now, but I've seen this bug.
Premise:
I use a Mac with Safari Crome and Firefox
WP latest version
PHP 8

For example, when I want to change the color of a text I get this screen:

See attach 1

Instead of this:

See attach 2

Do you know this error?
Are you going to correct it?
Let me know.

Have a nice day and thanks in advance.
