Invoice Missing items

[Sentro]

Hello,

I have an issue. Whenever i try to get an invoice of an order the products are missing.

Although the price is there and the total the items field is blank.
Once i download the invoice as a PDF it is fine with everything there.
Tried printing it...items still missing.

Searched the forum found nothing so please if anyone can help me that'd be great.

Thanks a lot
Sentro
