[tor-talk] ExcludeExitNodes not working consistently?

[Joe]

TBB 8.5 Linux.
In torrc I have: ExcludeExitNodes {xx},{xx},{xx},{xx},{us}  ...[xx are
examples - in actual file they are valid codes]

I also have a long list of countries under: ExitNodes {xx},... to choose
from / use.
I doubt it's having a problem creating a circuit with 33 other ExitNodes
to use (but maybe that's wrong).
But {us} is used quite often as ExitNode.

Q1: what type file should torrc be designated?  none, config or...?

Q2: Does there need to be a BLANK line between the default line in torrc:
GeoIPv6File
/home/chuck/.torbrowser/torbrowser-8.5/tor-browser_en-US/Browser/TorBrowser/Data/Tor/geoip6
and the next "ExitNodes" line?

Q3: AFAIK, there doesn't need to be a blank line between ExitNodes
line(s) and ExcludeExitNodes line.
Having a blank line or not between them doesn't seem to affect {us}
being used for ExitNode.

The only spaces used are between: ExcludeExitNodes {aa},{us}  [i.e.,
only commas - no spaces - separating each country code]

I'm pretty sure this worked to exclude the US as exitnode in TBB
versions before 8.5.  Any time I looked, US wasn't used.
