4.22 change the material sequence in static mesh LOD's

Hi! I created a project(it’s submitted to marketplace) in 4.21 with static mesh that have LOD’s and some material. If I open this project in 4.22 the sequence of the materials in the LOD(1-2-3) are changed, so the mesh looks like crazy!

Sorry for the bad English, and sorry again if this is not a bug!
