While inline editing to conditions missing fields (report and workflow module)

Trying to inline edit the fields to report module at contitions sub-panel.
Fields and values are randonly lost from contitions.

This is happen usually when more than one actions exists.

The same apply also to inline editing for multiple conditions at workflow module.
It produce an 403 error for URLs belong to randomly selected condition fields and json for module fields (insected using chrome dev tools)
