There is already a corrected multipart lm339 in core parts from 2019 (probably by request of the original poster, as I rarely submit to core parts 
from this post:
Better to use that one. Your part above is a generic IC not a multipart part which will have a number of problems.
The advantage of subparts in schematic with multi op amps (as in this case) is being able to move individual elements around like this. It is a lot more complex to configure but for multiple op amps in particular worthwhile learning.
In schematic I can move individual op amps where ever I want.
which is normally more useful (if as noted more complex to make.)
