Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
A photo would certainly help, but offhand I suspect that the dropouts aren't parallel to each other. Special tools are used to correct this, but there is some DIY. Without the chain on, bolt the wheel to one side only. And note where it ends up on the other side. Nowbolt it to that dropout only and see if the first side goes back to where it started.
If dropouts are parallel, either side tight will have the other in the same place.
The other possibility is what I see all too often on fixed and speed bikes is that people over tension the chain. Any tension is overtension and will pull the wheel forward or even buckle a dropout. The chain must be slack a all times with about 1/2" free vertical play in the center of the lower chord.
Need more help, post afewphotos showing the specific issue.
