What? you don’t need to do that. The OneStore folder is reserved for marketplace contents.
You are right about this, the marketplace version was published when the FBW team posted the version 0.6.1. But since a few Sim updates made the addons incompatible. They decided to pull the content from the marketplace, so nobody else would claim them again. Along with several discussion with the developer team about the licensing agreements for contents posted on the marketplace. The FBW team has decided not to republish the aircraft into the marketplace anymore. So whatever FBW version that you have claimed, they’re already yours in your “claimed” addon contents. But they shouldn’t be used anymore.
The invisible FBW aircraft is caused by the sim having to load 2 different versions of the FBW aircraft at the same time, one from the 0.6.1 in the marketplace, and one from the 0.7.1 from your community folder.
By removing the 0.6.1 using the content manager, you would also be removing it from the OneStore folder. But you don’t need to copy the 0.7.1 from the Community folder back to the OneStore folder. That’s not what they’re for.
As long as you only have 1 FBW aircraft, and that’s the one sitting in the Community Folder and nowhere else. You should be good. You’re lucky it works because both the OneStore folder and Community Folder are exactly the same content. But when you update the one in the community folder, the one in OneStore folder would still be an older version and you’ll end up having the same issue in the future.
Just remove the FBW folder in the OneStore folder, you don’t need that one.
