Updating State Tree global parameter

I’m trying to update or change a global parameter in a State Tree task so that it can be used in subsequent states. Typically, I achieve this as shown below:

However, the same approach does not work when dealing with an Enum:

Is this a bug, or am I missing something? I couldn’t find any relevant information online.

For context, WeaponType is an Enum, and the property I want to set in the State Tree is as shown below:

Running into this issue too.

I am assuming it cannot handle enums right now? Seems like a pathetic omission.

I got around it by using a struct but its a massive PITA to use when a simple Enum would suffice

Having the exact same issue in 5.5 but worse…

Like GPBF said, you can only get around it by using a sturct as seen in these screenshots.
This is still a bug in UE5.5, and I don’t believe it’s fixed in 5.6 either after looking at source.
