Not sure where I went wrong: downloaded your bundle, imported using Axe-Edit (3.2); it said IR in scratchpad, but scratchpad is empty (and preset consequently silent); saved preset to empty slot in XL+, but no IR to save (though I was prompted to do so) since scratchpad empty.
FWIW I've had no problem loading and using TAF preset bundles.
Hmm could it be a Quantum thing? I used the newest version of Axe-Edit for this. Probably FW19.
