Mine are also similar to yours. I don't think there is an RV out there that has perfectly aligned slides. If the seals are making contact and you are not having water problems you should be ok. Adjusting the slides can be tricky so be careful if you attempt it. Remember, whenever you adjust for the inside it will also affect the outside.
