xlookup to differentiate value "x" and value "x o" and return max date

Question

I've an excel spread sheet that is looking through a list of names. Many repeat. But to differentiate what a person has done, a " o" is added after there name at points.

I need the max date of the "name o".

This formula works (kind of):

=IFERROR(XLOOKUP(MAX(tblSchedule[Date]),(tblSchedule[Public Speaker]=[@Name]&" o")*tblSchedule[Date],tblSchedule[Date],"",-1,1),"")

But it also returns the oldest date for any 0(false) result and I can't seem to clean that up.

This is the table it is looking at:

Notice how the name Cr did find oldest Last Home date and Last Out date, but while the others had no " o", it returned the oldest date on the list (All 2/5/23).

I have probably answered my questions somewhere, but I keep missing it.

Any help is appreciated!!!
