I had a Den Leader accidentally check off the Pamphlet (req 4) and the Protect Yourself Rules (req 5b) requirements on Webelos rank, because he thought they were the same thing, in addition to CyberChip (5a).
In trying to remove the PYR completion date, I get the following message.
This elective adventure is being counted toward rank advancement. If you want to remove the date completed on this adventure you must have at least two elective adventures remaining to count toward the Webelos rank.
I think this may be a holdover from when Webelos required 2 electives? The scouts already have another elective that should fulfill requirement 3, so not sure what I can do to remove this.
