There is bug in sub-items table columns toggler on ezplatform-ee v2.5.13 fresh install: most of the labels are missing.

ezplatform-ee v2.5.13 is using ezplatform-admin-ui-modules v1.5.9. Columns toggler's labels come from table.view.component.js' headerLabels. Content Type is missing because table.view.columns.toggler.js is asking for “content-type” as a columnKey instead of “contentType”. Other blank labels come from unavailable columnKeys.

The bug is fixed on master branch via this commit and as been provided to ezplatform v3.x through EZP-31414 and its commit.

A new release of ezplatform-admin-ui-modules could be provided for the next ezplatform-ee v2.5 to take advantage of that fix, or v2.5 migrated to a new version of ezplatform-admin-ui with ezplatform-admin-ui-modules merged in it.

Best regards,
Adrien
