hi @FinestCreative ,
each string must be placed in the outliner box
7NOYROBLV6F8071CGG3W8U3K9
BZ8B289FOXJD2BI55721IRFZL
then the outliner will point to the asset which may have been disallowed
see post on how to find this. Quite possibly work the asset after exporting delete and reimport using
Importing Assets in Unreal Editor for Fortnite | Fortnite Documentation | Epic Developer Community
If this does not work, read post,
Asset Validation Issues - General / Issues and Bug Reporting - Epic Developer Community Forums
otherwise Just wait till epic Support
