utm Source paramters changing

[Caitlin_Poliksa]

I am setting up source paramters for PPC campaigns to the same asset. But I noticed something during testing that I have not seen before. 

When we click on the below link. The lead source changes…for example:
 
URL for Facebook retargeting:
http://www.adeccousa.com/Employers/salary-guide/Pages/default.aspx?utm_source=facebookretargeting&ut...  
 
The URL changes to this noting that the lead source is defaulting to “ad”
http://www.adeccousa.com/Employers/salary-guide/Pages/default.aspx?utm_source=ad&utm_campaign=2014sa...
 
Not sure why this is happending, anyone have any ideas?

Unclear. 

I wonder if there is a redirect rule or a GA tag value that's getting in the way here. I want to say the value is too long, but I don't think that's actually the problem.

Do you have a web person that can troubleshoot this?
