My Dynavector DV Karet/Ruby stylus is sideways

I have a Dynavector DV Karet/ruby cantilivier. When I am looking through my microscope during set-up alignment, and I watch the stylus set down on the platter, the cantilivier goes sideways and stops as if it is up against something. (It straightens out when running on a record, and the cantilivier angle seems OK.) When I lift the cueing arm back up, the cantilivier straightens out again. The music sounds good except excessive base and lack of highs. When I bought this cartridge I thought it was new, but there were tells that indicated it is not new. If I can determine that it means the cantilivier mounting is broken when it sets down sideways I would know where to go from there. The table and arm are Rega P-25, anti-skating and tracking force are currently set to 1.3 grams. This cartridge is first generation, now 33 years old.
