Sounds like a Javascript error is occurring. Do you have any other plugins installed? Also, could you check if there is any javascript error in the javacript console?
This plugin is causing the conflict: https://ww.wp.xz.cn/plugins/sierotki/
That’s what I see in the console:
JQMIGRATE: Migrate is installed, version 3.3.2

Thanks for the update. It’s probably because of the other plugin using another version of the Select2 JavaScript library. I’ve added/updated an issue about this:

Hi! Any news about that problem?
