GSheet Pivot find minimum date

[lizat]

I have a GSheets pivot table that shows me tag usage and the dates used, there is no need for columns I simply have rows defined for tag and date used. This gives me the list I need (almost).
I want to find the first date of use, so the second column of the pivot shows me all dates use and the first row for each tag, based on the sort, is the first use date.
With a small data sample this is feasible but I will have large data and I want a way to do this automatically. I have tried filter and can't - or am doing something wrong. Here is a small data sample

The Pivot data showing all dates for the tag:

PRow 1:Tag........PRow2: Date Used
----------........---------------
Dance.............1/1/21
..................2/1/21
Salsa.............3/2/21
..................7/2/21

And, this is what I want:

PRow 1:Tag........PRow2: Date Used
----------........---------------
Dance.............1/1/21
Salsa.............3/2/21


Any ideas?

Thank You

Ok. I think I had a caching or performance issue.
When I recreated using Values of Date and minimum it now works
