Cannot view Octed type in MIB Browswer

It is SolarWinds MIB Browser V5.0.153. I try to view the value of the this OID : 1.3.6.1.2.1.17.2.15.1.6.1 (Name : dot1dStpPortDesignatedRoot.1) from Bridge-MIB.

Actually, this value should be showing the MAC address of root bridge in Spanning Tree.

Is it possible to view this Octed type value ?
