Hi,

In various chips you have multiple equal functionalities packed together (eg. 4 NAND gates, 6 inverters, 2 op-amps etc.). This is the case on your schematics. There is no need to pay special attention to this, because they can be swapped (and indeed, the CAD programs can automatically swap them in order to route shorter traces).
So, don't worry about this (as long as the components library is from trustworthy source

).
