Dynamic event

Hey everyone, how are you doing?
Well, I have a form that I created with an input field of type number. In it, I’m using a dynamic "Blur" event where, in its action, I set a value in another input field. The thing is, when I leave the Actions editor and, for some reason, need to go back to the event, when I click on the action, the properties don’t show up (see the screenshot below). Could this be a bug, or is there some special reason for this to happen?

Thanks in advance for everyone’s attention!
