Only one filter applies?

Only one filter applies?

Hello!
I am forwarding mail to my zoho account from three different source accounts because POP accounts don't actually work as I'd hoped they do (the code which gathers POP3 mail doesn't merge the mail into the zoho mailbox; it keeps it partitioned separately)
 
So I'm forwarding the mail instead of POP3.  I set up 3 filters to catch the "To" address and take action based on it.  E.g. apply a label.
 
IF A MESSAGE IS ADDRESSED TO ALL 3 outside accounts, ONLY ONE of the filters is applied.  I thought all applicable filters would be applied, but clearly that is not the case.  Your filter-applying code stops after taking action on just the first one.
 
The message should have all three labels applied due to all 3 filters meeting the condition, in my view.
 
So, am I misunderstanding something?
 
thank you,
Linda
