Name of Sigma lens gets removed by LR

I recently bought a Sigma 50mm 1.4 lens and had to notice, that although LR is able to choose the right lens correction profile, it shortens the displayed lens name to "50mm". So if I export to jpg, the exifs only show "50mm" instead of "Sigma 50mm f/1.4 EX DG HSM" as it is displayed by other programs (eg. Mac OS Preview) when viewing the original cr2 file. This has to be a bug, since the Canon 50mm 1.4 and the 50mm 1.8 II remain their full name.
Although I'm glad LR at least chooses the right correction profile, I kinda dislike to use "50mm" as lens filter option, because that doesn't really say anything about which exact lens was used (well, in my case it does, as the other 50mms are displayed correctly, BUT that can't be the solution).

Setup: LR 3.6, Mac OS 10.7.2, Canon EOS 40D, Sigma 50mm 1.4 HSM

Remember that the labels in the two apps you show don't have to match up. Every app in the world that does this often has to extract an integer that hopefully identifies the lens, and then build up a description of that.

So, Lightroom has identified the lens, but it was not able to extract the full name sufficiently to provide a dependable string it could use in the UI. Certainly fixable, but more a symptom of the crazy abuse of metadata cameras insist on doing.

Ok, I understand the problem. Still, if LR identifies the lens (which it does, as it's applying the right correction profile) correctly, why can't it use the right name it already has to know (because of the lens profile)?
