Its wrong from the ply upwards, the 6mm ply is doing absolutely nothing, there should be insulation boards below the ufheating, hardibaker would be ok but 10 or 12mm insulation boards glued and screwed would be better IMHO, the mats should have then been leveled over to make a flat (even if not level) floor to tile to, using flexible materials throughout.
Can't understand why the previous tiler would notch trowel the floor then daub a few blobs of adhesive down and plop a tile on, its no wonder it a catastrophic failure..
