Hello MrSun ,
From the 2nd Image that you have attached.. It seems that Pin10 of Quad IC is connected to One of the Pins on the connector which indicates that the nets are being identified by the Altium.

Some points you can try:

1. Try zooming in on to the connector and nets shall appear
2. Check if there any compilation error. With Atlium 20, they have an auto compile engine hence Right click on the PCB Project and Click "Validate"
3. Try cross probing the Pins on the PCB and check if they indicate to the corresponding pin in the schematic

Share the results of above and this should help us to help you better.

Thanks.

There is a limit in Altium for components with many pins - when a component has more pins then the limit is set to, it will not show the nets. To change the limit go to System Preferences -> System -> General -> Advanced ... button -> PCB.ComponentDrag.ConnectionLimit and increase the number:
