Can't submit again in request history, new web portal

We are currently testing the angular based web portal, and when checking a request that is canceled or unsubscribed in the request history, we get a notifcation stating 0 Products have been added to the shopping cart, and thereafter the error message: The following 1 products could not be added to the shopping cart: 190922 [Insert product name here]. I have tried a lot of different products, and recipients, and two separate test environments. It works in the same environments when using the old web portal. Any suggestions? Version 9.2.
