As mentioned by 1980 TA plywood veneered boards are not the best quality around the edges this can be partly down to the manufacturing process or damage caused through transport and a good Cabinet Maker would not try and use this part of the board, but rip it off as waste, they would also visually inspect the surfaces for defects before spending time & money on edgebanding them, looking at your cabinets it looks like they have applied a thick lipping rather than say a 1mm discreet edging tape, this type of lipping needs a more expensive edgebander to apply it, so this may have been glued on by hand and the glue could have failed due to poor workmanship or a internal none waterproof glue was used which could not cope with the moisture in the air.
You could try removing the effected doors/panels and store them until the moisture content is correct and then have them refinished, or just replace what your not happy with.
