Is it ok to give mishloach manos that are 2 types of food but carry the same brocha?
There is absolutely nothing wrong with it, and it is totally fine. As far as I know there is no basis for these rumors. The Shulchan Aruch O:CH 695-4 says specifically that one may send his friend two pieces of meat. The poskim say that the two pieces should have a differ ant taste or be of a different type of meat, however everyone agrees that even though both are meat, which are the same bracha, that one is yotza the mitzvah l’chatchila.
