     - *[2] VF[1-9] is included under the VFI Custom Format.*
     - *[3] It should be noted that SUBFRENCH is included inside this Custom Format. However, SUB often means that the subtitle was embedded inside the picture (hardcoded). French releases tend to mix both, leading to some VOSTFR being labelled as SUBFRENCH and SUBFRENCH as VOSTFR.*
 
+	!!! tip "Indexers renaming in Prowlarr"
+		Some Indexers in Prowlarr can rename `MULTi` releases to `MULTi.TRUEFRENCH` or `MULTi.FRENCH`. I do not recommend using such a feature along with those Custom Formats as it can lead to false positives from the VFF or VFQ this Custom Formats.
