Do you have the same issue if you follow the OP’s steps to reproduce it?
Same problem, slighly different steps:
• Purchase the Bonanza G36 for your company
• Zoom to the airport where the G36 was delivered to
• Select any mission from there and “accept mission”
• Click “Management” –> Fuel and payload –> Manage Fuel –> Refuel
Provide extra information to complete the original description of the issue:
• No way to add fuel in the above mentioned dialog
If relevant, provide additional screenshots/video:
