Is there a way of preventing a Jenkins string parameter defaulting to the name of the parameter if empty?

Question

I have a string variable in Jenkins that has a default value of an empty string. When I build my job, the value is set to the last part of the parameter name. So our paramater qa-release that was set to an empty string now has a value of release.

Due to the way our code is written, I need to sometimes send in an empty string. We are trying not to install too many plugins so I would prefer a solution that wouldn't require that. I have tried setting the value to the following, but all produce the above results

• ""
• """"
• "''"
• " "

If you are talking about the String Parameter, in the last Jenkins version (but I suppose even from before) you can leave empty the parameter field when you are starting the job, and it results in an empty string value associated to that parameter.
