When copying cell with large formula, cell changes, but changes in outcome do not display

Hi, my issue is pretty much what I listed above, I've dragged to copy the formula below and it's listing all the right cell changes in the A column, but it's not actually changing the outcome of the formula until I click individually into each box and hit enter. This is feasible of course (only 1.5k samples), but I was curious to see if there was a shortcut. Thanks!

Formula:
=CONCATENATE(
(IF(1<COUNTIF('R1'!B$4:U$23,A3),COUNTIF('R1'!B$4:U$23,A3),"")),
(IF(COUNTIF('R1'!B$4:U$23,A3)," R1 ,","")),
