Trying to make select 2 taxonomy work for multiple

Hello again.

So next problem. I have set my taxonomies to be selected via the select 2 advanced option. I have said that the user can pick multiple (eg selecting tags etc). but I want them to see the options - even after selecting the first. But when they write the first one, the prompt get stuck on that one.

Here is a video to show what I mean: https://loom.com/share/f9b9b816ce7e4eb2aecfd68bc0884b07

Thank you!
