I am coming across an issue where Altium is shifting pin names to the left. When I updated from 15 to 16, I have noticed the issue come up. When generating the schematic from 16 to 17, the issues go away. No, I did not shift the pin names like that when creating the parts. Comparison between 16 and 17 preferences are basically the same. I have been using 17 to generate the schematic, however, I want to stick to 16 right now. Please look at the examples below. Does anyone have any idea what could be causing the issue?

The best way to do this in Altium is to use Net Ties. These will join two separate nets. See: https://www.smtnet.com/library/files/upload/NetTies-and-How-to-Use-Them.pdf
I will also occasionally use zero-ohm resistors to accomplish the same goal if there is a chance that I may need to break the connection to help troubleshoot an issue.
Have you checked the properties of your net labels? If they're supposed to connect to other sheets, you'll need to make sure the net label scope is set to "Global" to make sure all net labels AND all ports with the same name are connected together between sheets. You can change the properties of your net labels by going to Project --> Project Options --> Options tab and change the "Net Identifier Scope" dropdown to "Global". Then click OK.

Uncheck the "Render Text with GDI+" Go to: DXP -> Preferences -> Schematic -> General
Should work;-)
