Wordpress troubleshooter for a search filter function in a table existing of custom posts

We would like 2 problems solved and an explanation where we go wrong. Because we would like to learn from this. The first problem We use a plugin called Sorttable to generate a table on the page "Lijst". One of the columns is the taxonomy "psychologen_category". The data in this column is automatically shown as links, but these links lead to 404. We either want them to be working links, or no links at all. (and we really would like to know how you did it). We've tried several things: flushing the permalinks, deleting a href in the plugin code, several settings in registering the taxonomy, making a custom field that represents the taxonomy, but we didn't get a proper result. It is really imporantant that the data of this taxonomy is still searchable with the plugin Ultimate WP Query Search Filter, addressed in the second problem. The second problem We use a plugin called Ultimate WP Query Search Filter to generate the search box on the right side of the screen. Automatically, taxonomies are placed above custom fields. We want the taxonomy "Specialisatie" to be underneath the other search options (so below "Plaats"). (again, we really would like to know where you found it) If this is in your line of expertise we would like a quote for both the solution and the explanation. Thank you, Am and Li
