I've got the same mount as you (EQ5 Pro) and my polar scope also had the markings upside down. My polarscope has the new precision engraving pattern as per Tomatobro's second image. Essentially, I don't think it matters which way around the markings are. If you disregard the numbers and just align based on position using something like PolarFinder on Android (or an Apple store equiv) and use the StarAdventurer reticle type then you should be ok. At least that's what I used to do and it seems to work fine for me.
That being said, I couldn't keep looking at it with the numbers being upside down and decided to do something about it. In the end I was able to turn it around by essentially taking it apart and rotating the lens that has the markings on but it was a pain to do and certainly isn't something I'd do again if I got another mount with the same issue.
Unrelated, the other problem that I quickly ran into was that the EQ5 Pro has no polar illumination so when it's dark you have to shine a light across the top opening of the polar finder otherwise you can't see the engraving. I got one of these and although there not perfect as they've got no proper power switch, they made the process much easier https://www.firstlightoptics.com/sky-watcher-mount-accessories/polar-illuminator-for-eq3-2eq5-mounts.html.
