Creating a new engineering change order. After clearing default values from category and priority, when adding new Engineering change order, the first time this opens the detail page. However, when deleting the newly created Engineering change order, and adding a new Engineering change order again. The record is added to the grid and does not open the detail form throwing errors:

“Field 'Priority' must be filled in.

Field 'Category' must be filled in.”]

Issue has been addressed in the following link: Details for issue 811258 (dynamics.com)

It would be great to prioritize fixing this in a feature update.
