sef url problem

hi i am using sh404sef 2.3.0.988
1-inside sef_ext/com_customproperties.php copied to com_sh404sef/sef_ext/com_customproperties.php links are like that
www.didimmarket.com/index.php?option=com...g&tagId=5&Itemid=114

2-when i change from sh404sef configuration/bycomponent use joomla!router.php ank urls
like that
www.didimmarket.com/tag/5.html this must be
www.didimmarket.com/tag/didimmarket.html

so what is the problem? any idea?
Thank you.

There's a parameter in CP config that will likely solve the problem: URL Format.
You should choose 'Tag Name' or 'Tag Label'.

when i choose tag name its shows like that
www.didimmarket.com/tag/plajlar-didim_plaj.html (its shows tag name (-)and tag label with (_) )

and if i choose tag label its shows
www.didimmarket.com/tag/plajlar-didim-plaj.html (its shows tag name (-)and tag label with (-) )
(still tag name in url) but this time when i clik this label nothing showing in search list.

is it possible just like that
www.domainname.com/tag/tag-label.html
Thank you?

The problem is that tag value is not enough. There must be also the tag name.
Example:
You need to categorize soccer teams outfits. You'll end up having the following sets of tags:
Jersey => Red, Blue, Yellow, ...
Shorts => Red, Blue, Yellow, ...
Socks => Red, Blue, Yellow,..

If you have an url like www.domainname.com/tag/tag-red.html , which red are you referring to ? Jersey, shorts, socks?
That's why the tag name is required from a logical standpoint.
