Summary	0016014: Error when you submit an issue with an Email custom field not visible
Description	Error when you submit an issue with an Email custom field not visible
Steps To Reproduce	[Steps] 1)Create a custom field: Type: Email Mandatory: false to all cases Show on Report page: false Link it to a project 2)Try to report an issue in the project which the field was linked to [Behavior] Application error is shown: email invalid. [Expected behavior] Like any other field, it should not throw an error if the field is not shown in the page, because it's not mandatory.
