I believe I may have found a bug in version 1.0.1. While following the official tutorial step by step, I reached the FUEL page in the FMS. When I try to enter the Zero Fuel Weight (ZFW), the FMS always returns "INVALID ENTRY". Load via EFB. I have repeated the procedure several times and followed the tutorial exactly, but the result is always the same. My setup: Microsoft Flight Simulator 2020 A220 v1.0.1 No third-party modifications affecting the aircraft. Is this a known issue, or am I missing a required step before entering the ZFW? I've attached a screenshot showing the error. Thank you.
