filters problem

I log onto my spamcop webmail account from several computers. The 
filters I have set up from the home pc are non-existant when I check my 
filters from work, and do not work. I should have a total of four 
filters, two of which are the same, with different names, for mailing 
lists I'm on, but I can only see the ones set up on the specific pc, ie 
the ones I set up at work, I can only see there, the ones set up on my 
home pc, I can only see here at home. I noticed this when, at work, I 
saw messages in my held mail that should have been allowed through by 
the filters. When I went in to check the filters, they weren't there. 
This is becoming very frustrating, and more than once I've nearly 
reported a message that should not have been in my held mail. Is there 
any hope of getting this bug fixed?
