Hi there! Unsure if there is already a ticket submitted, but the Character Builder for Kineticist is missing Will Expertise at lvl 3. Admittedly, I’m a bit confused because the table on the Kineticist Advancement table (here) in Rage of Elements does not list Will Expertise; however, Will Expertise is listed further down the page here: Will Expertise. Just want to make sure which entry is accurate and if it could be resolved in Character Builder, that’d be awesome!
Thanks for reporting this! I’ve made a note or our team to take a look at this. 
This should be resolved now in both the table on the Kineticist class page and the builder.
