what our Friend is probably trying to say here is that east of here, the streetname, being W Main *Street*, should also be the same here.  I can buy that.
Apparently this is some sort of quality control, but following the example of uninformative notes seen all over.
(I've commented on some after taking the time to figure out if they,re legit or not, so  as not to waste the same time of someone else.)
what the heck, I'm waiting for the next incoherent ramblings to appear, not from this hemisphere, but more locally, so I may as well see how badly I can fix this.
The present TIGER background layer names this West US Highway 50, while the imported data has name_base as Main, with base_1 as State Hwy 50, and base_2 as US Hwy 50.
I can't see the actual TIGER 2017 raw data to see if it's changed, but for consistency, I'll work with the existing data.

To our Friend:  If you want your comments to be acted upon and not just ignored and closed, you need to be descriptive enough that anyone can tell what you mean.
This time I acted, other times you may not be so fortunate.
And further, you will find it a lot simpler if you don't open a bug-report, but learn how to fix these things yourself.
You have shown yourself to be capable of finding problems, but fail to explain them in an inviting way, or to motivate experienced mappers to actually mend things.
