"What you should expect from yourselves and each other" – This phrase is spoken to a group of people, but to each person individually. Particularly because it includes "and each other," it seems to me that "yourselves" should be changed to "yourself." This is referring to each person (hence, "yourself," singular), while the last part refers to everyone else in the group. This is someone else's work I am editing. If it's merely a matter of preference, I will leave it as is. If using "yourselves" here is incorrect, I will edit it. Thanks for your feedback!
