I agree it's the filter... but I don't remember ever having this problem, at least sooo obvious with my M6 and filters.
The choice between green spots all over the image and purple synthetic blacks is ludicrous.
Is there an easy way to correct the purple in PP?
Sometimes it's not possible to spot out every little green dot... try Piazza San Marco in Venice at night!!!

There is no simple solution. There are some profiles in Capture one that will go a long way to correct the colours, but that is as far as one can go. Otherwise - well, yes, cloning....
The reason for the intrusiveness of the reflections is that the filters are not simple absorption filters that can be muliticoated. They consist of dozens of layers of coating that reflect and reduce specific wavelengths through interference. That makes them indeed prone to have green highlights "bouncing about" Exactly this habit was one of the main reasons Leica could not use dichroitic filtering in front of the sensor - uncontrollable reflections between the filter and the rear element of the lens.
