Hi Dmitry,

I cannot reproduce that bug , I wonder why?

1. What template? please check also on Joomla Default one.
2. What Joomla version?
3. From what folder?

Please always give us more details, otherwise it's like walking in the war fog.

J4.1.5 HU2.0.10 SPPB4.0.1

Thanks for details. Correct me if I am wrong, the problem is only when you browse in "Folders" and use red DELETE button.

That's right

If you go to the media manager, through the addon.. Well, you can't delete several images at once, in principle
