Strange bug in ProtectTrackID

Hi guys.

I’m investigating a possible bug in ProtectTrackID as you can see in https://github.com/joubertredrat/Matomo-ProtectTrackID/issues/33.

I tested here with all PHP versions supported by Matomo and it worked fine, but I want just a double check to see that all is fine. Anyone can help me about it?

Thanks.
