"Subscribe by Email" Plugin Issue

We have ‘Subscribe by Email’ plugin activated on a number of our sites on the web.unc.edu multisite network. A user has reported that the last two blog posts had the sender listed as a user’s email address who is an admin from another website on the network (not an admin, etc. on the sender’s email). This admin does have Subscribe by Email installed on his site. After activating the plugin on other sites on the network and testing, this same admin is showing up as Sender (again, even though not an admin for the test site). We’ve also noticed that the “from” field is missing (seems to be commented out for multisite). Any suggestions? Thanks!
