WinXP.1 and winxp.2

When i updated to 3186 it added winxp.1 and .2 to my parallels vm configuration windows so that i have to choose winxp from the three choices before starting it. I dont know why the two others are there so am afraid to remove them because winxp.2 is the one with all the apps etc in it. but I select winxp to start it. Any reason not to remove them?
thanks.

 

I am in a similar situation; the only difference is that my applications are in winxp.1. I have no answer, but I am anxious to see if anyone has one.
