Synapse chroma studio

Hey people i was wondering if anyone else had issues with your own made chroma pattern completly dissapearing. I made one a while ago and it took me a long enough time to make. Now i bought a new keypad ( tartarus v2) and when creating a layout for the tartarus it was still good but after restarting everything was completly gone except for the tartarus v2 layout. Is this common to happen? Because then i know not to spend this much time anymore. (Yes im pretty bummed about this)
