Parent Pick Whip has replaced all layer attributes
I've got a weird issue that I can't seem to resolve.
As seen in attached screenshot, I no longer have access to the paremeters for any attributes at all. They have been replaced by a property pick whip. This is the case whatever project I am in, and it happens with any layer of any kind. I've even tried uninstalling and reinstalling After Effects but it didn't solve it.

It's all very irritating. I need for the attributes and paremeters of a layer to behave as they usually would. (i.e. that you can edit the values rather than have a useless pick whip)
Have I somehow changed a setting somewhere accidently that is causing this? If so, why did the setting persist even after I reinstalled the software?
I'd really appreciate any help as I'm having to use the graph editor as a workaround way of having any control over the various attributes of a layer - which is obviously ridiculous.
Many Thanks,
Adam
