I opened your scene and was unable to replicate the issue. Once it caches it does not re-cache it each time the frame is changed.
I also tried merging your scene into a new scene and again, no problem.
However, you have a scripted plugin "randomize elements" on your floor_light object, which may be sending improper reset notifications up the stack which could be causing the reset. Because you didn't include that scripted plugin with your file I cannot test it. Try deleting that modifier from your objects and see if the problem persists.
