This is not a PrestaShop core issue but a module issue .
The bug is comming from modules/ps_wirepayment/controllers/front/validation.php
Thank you for your contribution! Not sure or issue was were you have noticed, but I have shared your answer with a team and they have fixed. Later I'm going to share more details. Thank you!
Update from Dev:
There was a problem with checking quantities. In one place there was a condition with stock management but below the quantity was still checked and not taking of stock management status.
