Slides names and thumbnails

Hello!

I like this slider plugin. I use it with Gutenberg editor, but I have two issues: all the slides name are saved with the same name (in english is automatic draft) and I can’t rename it.

The second issue (I think it is) is with the slides thumbnails in the slider edition. It shows the same thumbnail for each slide, so that is very difficult to guess which slide is each.

Please, can you help me? Thank you.
