   Don't worry about it. The end of the tenon is end grain and contributes no appreciable strencth even if it bottoms on the mortise. I always leave a space of 1/8" or so anyhow so the extra glue has somewhere to go.

   I've got the PM mortiser and previously had a Jet bench top mortiser.  I think that all hollow chisel mortisers leave a pretty rough bottom on the mostise.  I do a little cleaning out with a bench chisel but, like Rob, my tenons are about an 1/8" shorter than the depth of the mortise so a perfectly clean bottom on the mostise isn't necessary.

   Indeed you want that extra space at the end of the tenon. Lets the glue go somewhere.Regards,
