Hi @dijix1990 - I've seen this before. Here's how you can fix it:
In 7.4.1 look under Configuration > Exporters > and find the exporter you are concerned with here, click on the Actions ellipse > View Interfaces > and on this interfaces page you can edit the interface Name, Description, Speed, and % Threshold. Note that if the "Locked" check-box is left empty, the next successful SNMP poll the SNA Manager makes against this exporter will over-write the info for this interface.
In fact, SNMP is most likely the reason you have these values there today. The 100 Kbps speed is somehow being reported that way, this commonly occurs when a "bandwidth" setting on the interface sets a value lower than the actual link is capable of.
