How to get Midi Remote to remember transport button assignments

I have a Roland A300 Pro midi controller. I’ve set up a visual representation on the midi remote and can assign transport commands to it easily. Each time when I close Cubase and reopen, Cubase remembers my controller and it is in the script list however all the transport buttons have lost their assignments. The buttons all react visually on the midi remote picture when pressed but when I hover over each one with the mouse it says “no mapping”. I have to edit the midi remote and redo all the assignments. It doesn’t make any difference if I save changes to the project I’m using it in. I’m using the latest version of Artist 12 in windows 10.
