Yes, it looks like a global problem in windows, in excel I can't perform a "fill right" (ctrl + R) or "fill down" (ctrl + d). To force the arrows into other directions (if desired), you will have to flip those components in your schematic and re-run the simulation. A note about Drawing Scale After designing a new symbol, you may find that it is disproportionate large or smaller than other components. From LTspice, under 'Tools', selecting 'Sync Release' will restore all of the new models in the latest libs from LTspice. To build my new IC, I had to build a new digital logic block.
