Why isn't my engine source code change taking effect?

Development build and I’m compiling the engine source using the same settings epic recommends UE5 and win64. The only thing I’m modifying is the steam sub system plugin. There’s a hard coded in value for the engine source code for lobby distance filter. I changed the filter to world, and I’ve tested this before and it worked. I recently tested older versions of my project using a VPN and now they’re no longer working as well. I’m wondering if Steam is doing something on their end, because now I can’t even get older builds to work on World lobby filter settings.
