Sessions problems from search

I'm having a couple of problems with search results and sessions. I've got a session being created that is called WASearch_WADAtbl_product and it is filtering the results as expected, but in order to clear the search results to display all products again I have created a page called search-clear.php which kills the afore mentioned session.

I've added a section on the page that should show when the session has content and hide when it's empty by way of 'WebAssist Show If'... but it's constantly showing and I don't know why!

Added to that, I have tried to show what the user has searched for, but all I am getting is 'Array'.

I seem to have a mass of search sessions available to use for some reason, but none of them are displaying anything apart from the session WASearch_WADAtbl_product, and when I kill it off, it still shows!

What have I done wrong? It's as though the behaviour of the upgraded DA has changed because it seems to be going something different to what I am used to, but I assume it's something I've done.

Files attached.

Thanks.
