UI bug: Pipeline parameter data types appear

While playing around with pipeline parameters:
I noticed that if I add a new parameter and start double-clicking in random place close to the pipeline parameter textboxes, I can make a data type section appear:

The documentation clearly states that pipeline parameters can only contain alphanumeric characters.
So I’m curious about this type box… Is this a hidden feature? How does it work?

I’m not sure how you got there, but you will see that there is an Open API tab in the pipeline definition where the type information appears, this is where that comes from. It is only used for the generation of the Swagger/Open API definition info.

This is a bug in the UI. It often happens when you rearrange the order of the parameters.

Thanks @dmiller. I’ve moved this post to the Enhancements category and relabeled to indicate it is a UI bug.
