Need help with Sidki filter causing problem

[Mele20]

This filter (Sidki 2008-01-02) is causing problems at dslreports forums:

[Patterns]
Name = "
... Remove/Hide: Ad Containers - Headers 7.10.30 [sd] (d.3 l.3)"
Active = TRUE
URL = "$TYPE(htm)(^$TST(keyword=*.(a_ads|a_adcont|a_adcont_h|i_level:[12]).*))"
Limit = 4500
Match = "]+("
"(> ]+)+>"
"( (^]+(>)\4)++{0,1} (^"
"|( )\#"
"))+*,$TST(\0=td$SET(#=)$SET(3=)|*)"
"|"
"(^$TST(\7=*)&$TST(\4=>)|$TST(\6=span)|$TST(\7=*.i_adtag:[12].*))"
"$SET(1=-hide)$SET(3=
"• \0-head\1: \4\2\3"

Here is a link to the thread started by another Proxo user:

When I disable the above filter, the problem with the odd looking post by lilhurricane in the thread disappears. The main Security forum page at dslr was also displaying very weirdly and I disabled web filters in Proxo and the forum page displayed properly. That was 12 hours ago. Since then it has sporadically displayed correctly even though I reenabled web filters and did not know which filter was the culprit. I have found the culprit but I don't know if the culprit was causing the Security forum main page weird display or not. I am certain though that the display in the bugs forum thread that is weird is caused by this filter.

I believe this is the same filter that about a year or more ago was causing the same problem at another site and I posted about it in Sidki's forum and he referred me to another thread and said it was fixed in the latest filters which I didn't have. So, I wonder if this is a somewhat frequent problem where this filter has to be tweaked?
