ERROR [ORNET-1017] _ "Unconnected pin, no FLOAT property ..."

I got this error on pin 14 of TI part LM63615-Q1PWP_TRANS which is a switching buck converter.  The thing is, that pin is supposed to be a No Connect and is defined in the part as such.  I can't figure out how to set the FLOAT parameter in PSpice for TI so the simulation engine knows that.

Placing a No Connect symbol on the pin didn't help.  In fact, the Help feature says as much.  (Why have the No Connect feature?)

Also, later got a different Error as I tried different things, ORNET-1103: Undefined FLOAT property 'FLOAT' U1 pin 'NC'

Finally found the three FLOAT property values in the Help feature and entered 'UniqueNet.'  This got me through to the simulation, which is taking a long time.  (I suppose I'll have to adjust the simulation parameters.)
