Clients/orders are not deletable anymore

Clients/orders are not deletable anymore. Ive done serveral test-orders, yet I cannot delete any of them anymore. Under orders/overview I still have the option to select orders and click „delete“, yet nothing happens.

Any ideas?

Kind Regards

Did you change the status of them, or did you create any documents for it? (Storno invoice for example?)

Nope, did neither of it. No generated documents yet, quite weird.

If you don’t get any failure message, I rather first try it from another Browser.
If you’ve tried it, also you can check the site in Development mode, and see what shows the system when you click on it.
