 Note the *double dot* after `altLabels`.
 
+.. Attention::
+
+    Due to a known bug from **TYPO3 v12+**, overriding the label of the empty select item via Page TSconfig (altLabels..) currently has no effect.
+    Track the issue here: https://forge.typo3.org/issues/100775.
+
+    Workaround:
+
+    * Adjust the label via a TCA override (for example by modifying the items array or using columnsOverrides/itemsProcFunc).
