I'm not an expert, but since no one has chimed in ...
First, I assume we're dealing with SEL. The commercial ride for ME requires some instrument work for your IR to be valid, at least for ME flying.
Yes, someone with an original FAA license would have their instrument rating "upgraded". I am not so sure about one issued as yours was. Your private / IR was issued on the basis of a foreign license. Your commercial was based on the "usual" FAR's. It could well be that the IR doesn't carry over. It also could be a horrible screwup - one that might take weeks to correct. I've called OKE City before about license issues and have found them friendly and helpful - where help is possible. That might be a good bet. If not, go through channels using the DPE and the FSDO (might be easier to just take the checkride). Good luck!
