How to get rid of tapered assignment in Physical Modeler?

I am trying to convert my Physical model to the analytical and it is failing at the integrity check. The error message says that members that do no support tapering have been assigned tapered properties. The member the message lists have indeed been assigned tapered properties by mistake in the past. But I went in the "Tapered Members" spreadsheet and deleted the tapered properties for the mentioned members. However, staad still complains about it and doesn't let me create the analytical model.

Is there something else I should do to those members?
