How do I update a dropdown token (and all associated nested tokens) upon pressing the submit button?

Hi, I am trying to perform a search in 3 different ways using a dropdown. Depending on which search criteria is selected, tokens from the relevant search inputs are all passed into the dropdown token ($multisearch$) which is then passed into the relevant panels to display the search result in table and raw event format. When I click the submit button after entering new text into a relevant search text field, the search does not update. I have narrowed this problem down to one of my tokens not updating (the $multisearch$ token from the "Search Criteria" dropdown). There is one quirk I found that makes the search update in the panels (for the default option only) but it is not a solution to my problem, when I click submit after changing my search and then click on the clear button (x) in the dropdown the search updates in all the panels. I think the reason for this is that the token is re-evaluated once the value is reset. Is there a way to force the dropdown token to re-evaluate every time one of the associated inputs is changed? Setting "Search on Change" to true for relevant inputs has no effect. I have trimmed my dashboard Source code as follows:

[^,]+),(?.+)?$" | eval firstname=if(firstname=="",realname,firstname) | eval name= firstname . " " . lastname | fields name ]]>$result.name$FooDashboard
