Basement toilet leaking - even after replacing ring

The house we bought about 10 months ago has a small bathroom in the basement with a toilet & sink and a plastic grinder/pump. Everything was working OK, but it didn't get a lot of use.

The toilet started majorly leading out of the base after one or two flushes. I replaced the wax ring - same thing. The toilet is on a small platform which is perhaps 6-8" high - so that it drains into the plastic grinder/pump box which is the type that sits on the floor - it is not embedded into the floor.

I suspect the float adjustment in the grinder/pump box, but my question is whether the wax seal on the bottom of a toilet is supposed to be completely water tight, and so in this case should be able to handle water in the toilet waste pipe as the grinder/pump box fills up, or, is the grinder/pump float always supposed to keep the level of the waste below where the toilet waste pipe enters it?

I don't want to lift off the toilet yet again and replace the wax ring again if I don't have to - so any advice on how tight the seal created by the wax ring is supposed to be would be most helpful. Thanks.

The standing water level must not be over the flange level. A sewage pump and tank should come on and empty out the tank before the level gets that high.

Test fit the toilet before final installation with wax ring. The toilet bottom should not touch the flange (could crack the toilet) and the toilet must not rock or wobble (will immediately break the wax seal).
