The user interface is blocked in TC Icon and I cannot load any new presets.
You have probably activated the preset parameter in the GPI page. If you are not using a GPI, you should disable it.
On DB4 and DB8:
- Go to the FRAME/SYSTEM/MAIN/GPI page and make sure that the parameter "Enable Recall" is set to OFF
- Go to the Frame/system/ GPIO page and make sure that the "FUNCTION" parameter is set to OFF
