Problem with regex filters

[xep22]

For some time now my regex filters are not longer working. For example this one for the subject:

Code Select Expand

^(Request|Question) for offer (\d+)$

The regex itself is correct. But Roundcube don't longer do the action I set up. Using 1.6.5

Sieve filters? Roundcube does not execute the scripts, it just creates them.

What do you mean ? check the attachment. And I am sure that worked for a while...

subject, fits to regular expression, regex

I'm saying sieve scripts are executed by a server, not a client. Roundcube is a client.
