Can you reproduce this problem? What steps will reproduce it?

1. Obtain a satchel from completing a preferred role in dungeon finder.
2. Open the backpack.
3. Receive error.

What is the expected output?

It appears that some checks intended for heirloom gear are causing errors when heirloom bags (i.e., satchels are BoA) are obtained/opened.

What do you see instead?

Visually, no significant issue.  However, BugSack/!BugGrabber catch an error.

What version of the addon are you using?

AdiBags v1.8.0-beta-10-gc5ee91a
+ AdiBags_Outfitter v1.4
+ AdiBags_PT3Filters v1.3-5.2

Do you have an error log of what happened? (Please enable the display of Lua errors or install an error-reporting addon to be sure whether an error happens or not.)

AdiBags is great, definitely my preferred bag addon, though the changes to sorting/columns/grouping are a bit odd and take some getting used to.
