Error when converting to mipmap

Hello,

Bassically I am making a paint texture for a plane in Microsoft Flight Simulator.  I am using a combination of photoshop and blender. So everything is working great and I make this: https://drive.google.com/file/d/1UQvNKTDslLbV7u0lAJc1CCYfhXeYgJ_e/view?usp=drivesdk

Then in order to make the texture work in Microsoft Flight Simulator you have to convert to mipmap. And after converting in both blender and the sim it looks like this:https://drive.google.com/file/d/1vhpUz3Zmm9yD2I1U6NIxYUrVid2OT2ya/view?usp=drivesdk

I have no idea why. Any suggestions would be helpful.

Thank you for your time.
