You have a CMS webfeature that previously had a segmentation applied to the properties. When trying to change the Auto Segmentation to No Auto Segmentation, this does not save and instead shows the previous segment.
We are currently evaluating this issue and will update this article when we have more information.

Navigate to Content Management>Site Structure>Folder View
Search for and open the Web Feature to apply the auto segmentation
Click the Advanced tab
Next to Auto Segmentation, select No Auto Segmentation from the dropdown
