Advice on Phase Problem

[PMST]

Hi!

I need a bit of advice from someone that cuts lacquers (or experience in this...). I have mixes from a band who are looking to get the tunes mastered to vinyl, however the songs were sounding pretty thin and before doing anything I checked the phase and found that everything above 2khz has reasonably bad phase problems throughout the entire song. At no point does the correlation meter reach back up to 0.

I know phase problems in the low end will cause problems, but this is an issue in the high end on this track, so wondered if someone with experience could offer any advice? Is this going to problematic? I've already suggested a remix but I'm not sure its possible so i wanted to try and find out more information from others with experience in lacquers.

Image attached, this is the closest the high end gets to 0.

Thanks!
