What do you mean by "it works when deployed in test" and doesn't through the access point? Too vague, but my first thought tells me you are saving to test using the client and when you open it locally from test with the client it behaves well, but when you access it through the access point it does not. Still vague and to me not possible unless different versions are being used, or expression syntax issues. Can you provide some example data/qvw that shows this, or screen shots (with proprietary blurred).
Does both the servers have the same Qlikview file?? i.e. both in the test sever and the other server your applying filters?
If yes, did you apply all the filter in both the files and check the output ...if you still face the issue please share us the screenshots so that it will be helpful for us to understand the issue
