When you are trying to add columns to the table widget we have a few columns with “project” wording, like Project Status, Project Description, etc. Ideally, when you search for some wording in the columns panel, it will show all columns containing that wording, however, this is not working as expected in the report designer.

When searching using a column picker it will search for object as well as attribute label that matches your search. Those other fields are showing since it is part of the project object. To narrow down your search it is suggested to search for Project Status or Project Description specifically.
