Transitions does not work when url includes "&"?

Transitions does not work when url includes “&” in my Piwik.
For example:when try to view the transition of the page “http://www.mysite.com/ad.html?pid=123&mount=134”,it shows
There’s no data for http://www.mysite.com/ad.html?pid=123&mount=134
It seems that the ‘&’ in the url is replaced by ‘&amps’ for query
Mysql executes sql like:

select idaction, type, name FROM wd_log_action
WHERE ( hash = CRC32(‘mysite.com/ad.html?pid=123&mount=134’) AND name = ‘mysite.com/ad.html?pid=123&mount=134’ AND type = 1 )

and returns null;
Is there anyway it can fix?
Many thanks.

if you look in the table log_action you will find that the URLs / action names are stored in HTML entitied format. So it’s expected to see   here. Maybe it helps?
