For some Flex Packs / Presets work anymore in FL 20.8. - message you have to update to a NEWER Version

Hiho there,

after updating my FL - Studio to FL 20.8., some Flex Presets don´t work anymore in FL 20.8. - message shown :
"you have to update to a NEWER Version" !?!? (see Screens. attached).

These are presets that are included in my favorites, now and before on another PC and imported like Saifseemer told me.

MOST of my presets work, only a few of them not (I have them all in the same folder).
Here are two examples:
- LD Sharpie
- BS Phatty Stack

This preset works when not choosing it under favorites, löike choosing it from the "Black Octopus ... Pack "

for this Preset, I don´t find it in Flex any more, so f.ex. searching for it in all Packs Flex doesn´find it any more!?!?
- ARP Electric FM

Or is it that some are simply renamed??

Best wishes
Jey
