Hi @JomarGF ,
Do you mean that no matter you choose which collection, it will always display the first collection on the right hand?
That's a little strange. I didn't meet this kind of question before.
Firstly, I suggest you check whether the data in the collection is right.
You could check your collections by adding galleries, setting the galleries' Items to collection name.
In this way, you could know whether the problem is about your updating collection's formula.
Then, I suggest you check your browser.
Please clean your browser's cache, update it to the latest version, try other browsers.
I believe the mainly problem is about this.
I think there's definitely a bug because many people have reported this issue. Here's a link to a recent thread.
@JonathanGibbs has reported this issue so hopefully we'll see a fix for this soon.
