Materials not applied after Migrating

Development Asset Creation
,

Hi there :wave:,
After i migrated a big amount of assets a problem occured where some Materials are not applied.
Meaning the textures and the node structures are all contained in the migratet material.
But to make the material show up instead of the default grey Material, i have to go into the material and move any node slightly just to be able to click on “Apply” .
And after that the material is shown on screen working just fine.
I wonder why this happens.
Was the migration not successful or did i forget something before migrating?

And of course: is there a fix to this problem? Maybe by applying (compiling) all the materials with a few simple clicks?

Thank you and best Regards!:wave:
