You appear to have SI BSim GHz, SI LSim GHz plus the "combination product" SI PI Bundle which includes both BSim / LSim and other options e.g. DC Drop. (I'll admit that's a simplified description!)
Your floating licenses are flexible - so it is not possible to identify whether one users "BSim" license is from the BSim product or the PI bundle. in fact, it does not really matter.
If you are only running out of "hypbswsiext_c" licenses, then you probably need more "HyperLynx SI BSim GHz" licenses. If you also get "denied" messages for other licenses, speak to your account team to work out what is the best product to give you the additional licenses you need.
