Am I stupid or do coin flags give more drops in these areas in Pet Simulator 99?

I place a singular coin flag in some different areas and all but one area make the drops go faster! Do people know about this and I am just stupid, or is this a bug that I found? Please tell me!

I tried looking for videos about this on youtube, but I did not find anything about this and still don't know whats wrong with the drops and coin flags. If you have any info, please let me know about it.
