The 'AllowDeletion' attribute is not declared.

For two days, I've been trying to get on to creating SiteTemplates in SharePoint 2016. When I'm creating the template, I get the error message as saying. "The 'AllowDeletion' attribute is not declared.". It comes from  SiteCoumns that I inserted them into SiteCollection. I have opened the cab file from wsp and then find fields containing attributes such as <FieldRef ID = "{23c92184-aa69-47ed-8685-2a9e7ac66c86}" Name = "ArendeType" AllowDeletion = "TRUE" /> All columns and content types were created in the same SiteCollection.

Is there enyone that can help me on this. This is a section of the ElementsContentType.xml file in the cabfile for the site template (wsp-file)

<ContentType ID="0x010100E24BBAB22E21AB4BB8CA45C9D77AA9B9" Name="PDSAdvokat" Group="PDSAdvokat" Overwrite="TRUE">

I got the anser that this is a bug in SP and the solution is to open the wsp file and delete the attribute Allow delete. This is from my point of view not a solution and the problem has ben since 2013 so Microsoft chame on you.
