Problem with tags [solved]

Hello.
Today a window for selecting tags looks strange:

For example on this page https://en.numista.com/catalogue/pieces187134.html
And I can not select more than one tag.
This is on the computer. On the mobile phone - ok.

Also for me a window with engravers is inactive.

Edit: additional information.
There is no such problem on the home computer. However, both computers have the same browser (Chrome) and the ad block is turned on. And before, of course, there was no such problem.

Looks like a 'You' problem, I can't replicate it.

There seems to be a similar problem in the French forum.

That's it, my problem has been solved, tags are added normally.
Thank you.
