Problem: After updating Toolset plugins, some Views are not filtered as expected. I am displaying only the results of these Views. In the past, the Views were filtered by taxonomy term using a Query Filter, but I am unable to modify the taxonomy Query Filters now. I see a message that these filters are controlled by front-end search, but I do not display any filters in these Views.

Solution: In this case, it seems that the Views were created with front-end search filters but those filters are not displayed on the front-end of the site. Those front-end filters should be removed first. Edit the Views and delete any taxonomy filter codes from the Search and Pagination panel. That will restore your ability to modify the taxonomy Query Filters, and you should then be able to select a specific term to use for filtering each View.
