I found an old link https://buddypress.org/support/topic/auto-complete-not-working/

Not sure how to implement the fix, or if I need to; I’m not seeing @suggestions in my forum and I’m not sure if it’s theme related or the plugin. Also I’m still learning wordpress, how to implement the fix @mlwilkerson described would be helpful.
