A picture of the stand on the bike and a description of what the problem is would help in trying to figure out a fix.
I have one of those and never had good luck with it as it interfered with the hardware for pulling a trailer. What is better I think, is a center "butterfly" stand. But maybe we can get what you have to work. Post a pix.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
