Deleted Items still show in my group

I disabled cache + plugin and enabled the plugin
Cleared cache and used different computers (Mac’s)
Also used different browswers.
And I do have a STW paid account.

Trying to delete 3-4 items from my groups but even though I click confirm for the question “Are you sure you want to delete “BB Remessas” from your portfolio?” it never updates. I still see those records.

What am I doing wrong?
