Kato HO scale shorts out when more than 1 power track, running Digitrax DCS 52. How to add more power track feed and avoid shorts?
Is your Rail A, Rail B wiring consistent?

Kato Unitrack switches have two screws in the bottom that you can use to change them power routing (the factory setting) to non-power routing. I suspect changing them to non-power routing may solve your problem.
After that, you might fasten the track in a few locations with tiny screws. Once it’s assembled, it’s quite solid, so you really just need a couple spots to keep it stationary.
This is a very popular brand of model train track system especially well-suited for N scale and HO scale trains.
