Mission_Item message error when Mavlink forwarding is enabled on custom qgroundcontol build

Good day,

I am building the cubepilot qgroundcontrol - the only modifications I made on the software is changing some icons.

Build is based on the 4.4.3 branch on the repo.

When I enable Mavlink forwarding I get the errors that Mission_Item is sent instead of Mission_Item_int and the same for Mission_Request

Any advice?

TIA
