Report (in the last) 2 hours doesn't work

Hi,

I try to create a report with:

responded is in the last 2 hours

But that doesn't work, I can only go down to days.

Even tho I used exactly what the flyout suggest "e.g. (in the last) 2 hours"

see below, it keeps the red surrounding and can run the report:

My original need is to get Issues not responded within a certain time (base on priority)

the SLA feature of GTA is what we consider SLG (Goals) but the SLA is responded within x hrs. So want to report on it.
