Why would not all of my "Fix Release" values not show in JQL dropdown when configuring Kanban Swim Lane?

[JanaW]

I have several stories that have a value in the "Fix Release" field of "WFX Mar 2014", but when I go into configure my Kanbanboards swim lanes to configure and I put the JQL filter in to pull those stories 1) It doesn't show that value at all as I start to type and 2) it gives me an error of "The option 'WFX Mar 2014' for field 'Fix Release' does not exist.

Problem Solved: Although we couldn't see it in the Fix Version, ther were a couple of spaces where there shouldn't of been in the Fix Version. We found it only because we were using Project Configurator and it showed a discrepency between our Dev environment and Production for that field value, which made us take a closer look and found the spaces.

I just learned too that the Project lead, actually changed the value of the field for all the stories that should now have a value of WFX Mar 2014" from another value this morning. Could this cause an issue why it's not recognizing the new value in the JQL?
