Talent perks not showing on grenade

I started 4.0 with full trainings, which includes 30% crit chance for grenades - lvls 12, 18 and 28

My lvl50 epic grenade, with 3x epic +12% crit perks and 1x 'strike' fire grenade perk (+6% crit), now shows 67.6% crit chance (base 10%, talent 0%, perks 42%). The 30% from talents isnt showing in calc

PS; the dmg and range perks from talents are showing

With base 10%, perks 42%, training 30%, it’s because 10% plus 42% is 52%, but then x30% to 52% is 67.6%. Not sure if that’s intended, but I hope not.
