{$NET.IF.IFOPERSTATUS.NOT_MATCHES} macro that is used in LLD of network interfaces is using value ^7$ with description "Ignore notPresent(7).". However:
1. LLD data contatins operational statuses in textual form (unknown, notpresent, down...).
2. In discovered interface we convert these statuses to numerical data, but there is no "7".

Macro value should be changed to ^notpresent$.
