createinstance() bug??

I think there is a glitch with createinstance();.

createinstance(node("/Rack42",model()),model());

when referencing a rack, and i create an instance of that rack, the number of bays is not consistent. seems like it adds a tenth digit. 6bays(original) = 16bays(new instance). 14bays = 24bays(basic table says 24 but has not been applied yet...). STRANGE.

can someone check this?

createinstance() is used to create instances of library objects.

If you want to make a copy of an object that is in your model or a userlibrary, use createcopy().

Thank you for the quick response! Sorry for asking so many trivial questions. >_<
