Morning
The Android client app created new tickets on tables when adding new orders. It started doing so after updating the app to the latest version. I have to merge tickets on the table before I can print it. I am trying to get screenshots and will update here if it continues.
Latest version on appstore is 2.0.53 and I just tested it and it did not add a new ticket. It let me add orders to existing tickets. I wonder what is happening with your config.
I think its specific to your setup, you may have some automation causing it. I have been trying to reproduce it but I can not make it do what you said.
