"Product not in stock" message AFTER order confirmation

[iWim]

Hey hey,

I have a weird issue. Don't know if it's a bug or something with the payment plugin. I have also contacted them just in case.

When a customer wants to pay with iDeal and confirm the order they go the thank you page with a note that says ,,Please wait while we send you to iDeal".

Then for a very short moment a page with the message ,,Attention: Product is not in stock [product name] is displayed.

The page will then load to iDeal like it should and everything continues like it should.

My client believes that some customers may cancel payment because they notice that message.

I have added the image of the message as attachment.
The message is in Dutch, translated Attention: Product is not in stock.

Is this a VirtueMart issue or ccIDEAL?
Do you know of a solution?

J 3.4.5
VM 3.0.10
ccIDEAL 4.4.9

Thank you.
Wim
