You're right about the listing and it surprises me that it didn't air in Canada as Canada were the first to work on getting the TV series into the West.I didn't get cable and YTV until September 1998 and don't recall Ranma airing then. Don't see it listed here either. It must have aired in the US where it's highly certain to have been censored.
Can not comment too much on physical released since I didn't buy too much in store. I did buy Cowboy Bebop volume by volume back when Future Shop was a thing. Also bought the Vision of Escaflowne movie from Future shop. I remember having to return it due to a defect in the disc. Their entire batch of DVD's was defective. Eventually I did watch it online, hopefully legally.

Pretty cool that French audiences got to see in in 92' as the series had just finished their last episodes around that time.
My theory would be that Latin American countries likely took the VHS releases and censored those. The quality of the Mexican version looks like a VHS rip and it seems like ripping the VHS would have been easier than the DVDs.
I can empathize too with products coming in damaged and feel a loss there. Kimagure Orange Road TV I order from Discotek on Blu-ray with the confidence everything was playable as I've never had a defective blu-ray. Well, 7-months after buying I watched it and disc 3 was unplayable. The marks were barely visible and my only conclusion was that this was a factory mistake as it was well protected in shipping and none of the discs were dislodged.
