HI @anthos314 : Improper anti-skating is a very common cause of cantilever skewing, but your photos seem to show some skew without the cartridge being on an LP, also I wouldn't expect improper anti-skating to cause the suspension to develop an offset to either side after only 2.5 hours.
In any case, you are welcome to return your Delos to us (via the dealer that you purchased it from) so that we can see and correct what is causing the issue.
kind regards, jonathan
