Cannot Move Modular item

Not sure when this started happening but on sites that I’ve upgrade to the most current version of Grav (1.7.17) and The Admin plugin (1.10.17) I seem to have lost the ability to move pages/modular items either via changing the parent or the move icon.

When trying a get a “Failed to save entry: Forbidden” error, this is happening both locally and on the server deployed versions

I’ve narrowed it down I think of having Flex Objects Directories Pages (Admin) Enabled,
If I disable this then I can move objects with no problems
