Strange issue with workflow imports (using latest version of ComfyUI, master branch top)

When importing some workflows, I assume from older versions of ComfyUI, all of the "inputs" which were and are supposed to be widgets are all concerned to inputs (the dots).

Not a single widget in the workflow.

I can manually go through and do "Convert Input to Widget" on these broken inputs, and the data they originally had comes back, but it's very painful to do on complex workflows with dozens of nodes.

I'm assuming the json format changed in how nodes are described in workflows at some point.

I can probably write a script to fix-up old workflow json to fix this issue, but I'm not sure what changed, or if there is a way to fix this already?

Anyone else encounter this issue?
