We recently added 2 new fields to a portlet and added them to the Filter section and the list section.
All the users are able to view it in the List Section.
The newly added fields are available in the filter section only for few users.
Others are not able to view the newly added fields in filter and unable to configure manually as well.
While configuring the fields manually the users are not able to save after the new field is added.
Thanks in Advance
