You have to add the: “PWR_FLAG” symbol to the Vcc net (and probably also to the GND net. Search this forum for “PWR_FLAG” to learn what it is and how it works.
Also regarding the need for PWR_FLAG (@Curtis_Newton seems to have sorted, but I’m adding this to others who find this thread searching for help), there is this useful FAQ entry:
Personally, because PWR_FLAG is necessary in some cases I like to make it necessary on my schematics for all cases for consistency reasons. Especially since I use the PWR_FLAG symbol as documentation for the source of power. Thus, even on power regulators I use power input type pins on the outputs. If you want to also follow suit, please recognize that my technique will then no longer trap the error of connecting the output of two different regulators together.
You can also edit the connector and save it locally for your project, as a power connector with the pins properly categorized. Then you won’t need the PWR_FLAG hack (which only adds a token output pin to a net otherwise consisting of all inputs and passives).
