I have processed the baseline for GNSS observations, the results of the baseline process have been fixed but there is a red mark for the vertical point tolerance. What do these red flags mean and how can I solve this problem?

Are there coordinates assigned to the vectors from the imported file? Take a look at the points and see if there are imported coordinate values based upon the here position. My guess is that you have conflicting vector and coordinate values based on your "here" position at the base versus the control value that has been assigned. You can disable the coordinates and use the vectors from the control value you have assigned to the base location, but honestly this isn't really enough information to diagnose the issue. Perform a point derivation report. This will usually give you an idea of what the culprit might be. It is a bit odd that the vertical varies as much as it does.

My guess here, and it is only a guess because the OP hasn't provided enough information yet, is that a CSV/text file was imported and it had ZERO elevation values instead of blanks. If that's the case, they would need to edit the coordinate for each point and delete the elevation so it's just blank, allowing it to be held for N/E but ignored for Z.

If that's really the case, then the proper elevation of P2, for example, would be close to 23.7m.

That said, need to see point derivations to confirm.
