SquidGuard don't filter.

[acc4all]

Hi Everybody,
    I'm newbie in Pfsense, currently my SG can not filter extensions, my pf is 1.2.3, squid 2.7.9_4 and squidguard 1.3-03. My conf:
1. First ACL "blk_Media": Dest Regex "..(mp3|wma|flv)($|?)" to bock media file and more
2. Second ACL "blk_Exe": Dest Regex "..(exe|msi)($|?)" to block Execution file

Problem:
1. ACL blk_Media can filter media like mp3, wma.
2. ACL blk_Exe can not filter file like exe, msi.

if i create more ACL, only first ACL work. Any problem with my config? I attacted some screens, pls help me fix it.

Thank you, dvserg! You are best.
I got my problem here:

0-order A_rule for Source 10.0.0.0/24

1-order B_rile for Source 10.0.0.15. In this situation

In this situation B_rule never applying for 10.0.0.15 source, becose A_rule already worked
