There's a possibility that I just missed something in the wiki (though I combed through it several times before giving up), but there seems to be a bug when you have descriptions set for each result in Paths.yml and use /ar view to view a path. The first description ends up being used for each result in the command output rather than each result maintaining its own description. Here's a snippet of Paths.yml that I'm using:

results:
command:
value: broadcast &p has just ranked up to Explorer!
options:
description: Announcement of your rankup!
command2:
value: eco give &p 10000
options:
description: Receive 10000 munnies!
command3:
value: acb &p 5000
options:
description: Receive 5000 claim blocks!
command4:
value: pex user &p group set Explorer
options:
description: Receive the Explorer title!
message:
value: Congratulations, you now have the Explorer rank!

Here is a screenshot of the results given by /ar view for that path: http://prntscr.com/khu5pl (this was tested with each path created). This was tested on Spigot 1.12.2 with Autorank version 4.2.5 and 1.13-R0.1-SNAPSHOT with Autorank version 4.2.6. Thanks in advance, let me know if you need more information.

Thanks for reporting! I'll look into the issue.
