Trying to analyze chess.com games with fritz, can't get rid of crazy timestamp formatting

So I uploaded a PGN into fritz with timestamps because I'd like to have the number of seconds each turn took, unfortunately, this is what it looks like

while I want the number of seconds, for the life of me I cannot figure out how to delete the [%timestamp] crap, nothing works unless I delete all commentary which only leaves the turns and no number of seconds, is anyone familiar enough with this software to have any idea whats going on here?

There are a few different delete options in Fritz, I assume you've tried those and none of them are what you want.

One option is opening PGN in notepad, and then edit -> replace.
put %timestamp in top and leave bottom field blank, then click replace all.

I believe when you download chess.com PGN it has %clk and not %timestamp. Maybe Fritz adds that automatically. By similarly editing the PGN (e.g. removing %clk) but this time before pasting it into Fritz, maybe that will get you what you want.
