In my case, I have a repeater named "my-property", containing several properties.

And another property (not in the repeater) called "my-property-something"

When I try to set-up a search service, this property is not available because GetCommonMetadataAction think it is a repeater.

The problem is in

org.ametys.cms.contenttype.GetCommonMetadataAction._getRepeaterChildrenNames(Map<String, MetadataDefinition>)

The property is considered as a repeater if

StringUtils.startsWithAny(metadataPath, repeaterPaths)

(which is the case with the name of those properties)
