Hi all,
Has anyone ran into this issue before and found a solution? I was building a workflow and then out of the blue, when I added a Filter, this came up for the Filter Configuration.

I am not able to configure the filter as it just shows the programming language behind the configuration.
I have closed down Alteryx, reopened the existing workflow I was building as well as tried to open a new workflow. This XMSG still shows and wont let me configure the Filter. Any ideas?
