Not A Bug Spellskite and Kolaghan's Command. Cannot change target

[Xargus]

I should be able to change any of 2 Kolaghan's targets to Spellskite as it is both artifact and a creature (pay for each separately). There are many rulings on this already available. In MTGO I cannot do that though. Cost me some games already...
