PowreApps collection not cleared after closing the form

[BrittanyR]

I closed the form, closed the browser, started it again, and I still see 4 collections when I go to File > Collections. 

I would like to reset my collections (remove them), because I added few columns in SharePoint, my data connection is updated, however my collection that's based on this data connection isn't picking up the new columns, I ran the clearcollect again, it's getting the new items from the SP data connection, but not getting the new columns. Any way to refresh the collection to pickup the new columns from the SharePoint connection?

I just tried it, didn't work. I removed the SP connection and re-added it, no change. 

The variable I have it populate using a Set function, upon a choice from a drop-down, if the user chooses "Sales" or "IT", and based on their selection I fill the collection with items from either Sales or IT.. both lists are the same, with same column, same internal/display names too.

Hi @BrittanyR :

Do you want to remove these four collections?

The only way is to delete the formula that defines them.(If you use multiple formulas, you need to delete all of them)

Just delete the formula that defines them, and then confirm that they have disappeared in File-Collections, then you can create a new collection with the same name.

Best Regards,
