Boolean "Not" Node Not Switching Proper

Running 4.18.2

When using a boolean “Not” node, bool is not always switched.
Images attached.

In same image is a bool switching from not to true which works correctly. Later in execution, when Filled=False, “NOT” works correctly again.

Hey,

I reproduced this in a blank project and the NOT node changed my bool to false from true. Could you send me a project where you got the reported bug to repro so I can take a closer look.

Hey,

I am marking this as solved for reporting purposes. If you need any more assistance with this please comment/respond here and it will reopen your question.

Thanks
