I know this is only one source, but after reading Harry Yeide's "The Tank Killers" about WWII TDs, it seems clear that its really down the specific HE round used. There are anecdotes of TDs at close range having to fire multiple HE rounds just to make a hole big enough in a gutted stone house wall to use the structure as an improvised vehicle emplacement. It might be realistic to assume the shot is simply passing through without hitting anything hard enough to detonate it.

Possible IMO, members of Cpat. Mackay's group from Arnhem specifically described how they were assaulted by Tiger II's - the tank was apparently firing Panzergranate only as the shells went through the entire building, leaving large holes in their path but not exploding.
