Vendor attributes are not available after the import with WP All Import

Is there a simple way to import Vendors attributes ?
I have successfully imported 2000+ vendors with WP all Import, but the attributes are not visible.
Yet, i made an import of the demo file in order to map correctly the columns and everything looks right in the sample view.
But after the import is done, no attribute is visible (on the front and on the back).
Thanks for your help

Please make sure that the imported values are correctly mapped to meta fields and taxonomies (with “hp_” prefix). If so, then this may be a caching issue, please try temporary disabling HivePress cache using this code snippet Disable the HivePress cache #hivepress #cache · GitHub
