In order for the portal to display the cleaned metadata instead of the original one, it is necessary to declare it in the Homepage and Search page administration interfaces.
Metadata is case-sensitive. If the case does not match, Fluid Topics does not take the declared metadata into account.
The new metadata key will not have the same name as the original one, e.g., the foo metadata element's new name will be foo_custom. It is important to replace the old name with the new one. Otherwise, the metadata value will appear twice in the portal.
