Super Trader Trophy not unlocked

[Juras]

I left Super Trader to be my last trophy to get nice pop up screen of my choice. To do it after getting all Ryno Cards and missing only one standard card i do not check my card collection till i unlock all others trophies.
Moment I choose to unlock last trophy was Snagglebeast Boss fight (3rd run/2ng challenge run), gone to game menu, clicked Cards Collection, last missed card unlocked and boom-no trophy. All cards was unlocked, 100%, full 33 sets in stats.
Things to note- I had uncompleted Ryno Cards delivery quest at current playtrought.
Next thing I did was to load my backed up save from end of 2nd playtrought (1st challenge run), and voila, after checked my card collection and unlocking last card (same one as before) trophy imidietly popped up. ( Ryno Cards delivery quest was completed at this playtrought)

Looks like its very rare glitch but may happen and better back up save before triggering trophy.

I have 33/33 and 100% duplicates and no trophy. I am glitched out of the platinum.
