Any UR (including speed limits) submitted by anybody takes time to show up in the WME. When it does, you have to manually confirm that the speed limit matches the road segments, just like any other UR.
If you want a less tedious way, you could always try the ITO Map. If you find the correct road you’re looking for and click on it, it shows a blob of text. The speed limit of that road is somewhere there.
P.S.: I am also Rank 1, I feel your pain!!
