Ionic app getting previous builds

My app sometimes gets stuff from old builds, that aren’t in my project anymore. I’ve tried to remove the www/builds folder, the sourcemaps, clean the Windows Temp folder, and pushing only the essencial parts of the project to the Ionic Pro to build a cleaner package, but none of these solved the issue. Does anyone knows what may be causing this problem?
