Hi LOFderKruiden67 and psychicBOY
If you did what Salva said and the issue still persists, I have to ask you to open a private ticket and provide us with your website credentials in order to take a look as I couldn't reproduce it in my staging site.
Better if it's a staging site in order we can make tests, if not, probably we will need permission to download a backup.
This is the link to open the private ticket: https://stockmanagementlabs.ticksy.com/
And remember to make a reference to this post.
Best Regards,
Andrea.
