Unable to allocate MODs to Krrstantan

I'm having a similar issue (though I can assign Mods via "Advanced"). However, the basic assign doesn't work on the circle and plus (I suspect) due to Krrsantan only having two 2-set mods listed for him. All other characters have either a 2-set and 4-set recommended (e.g. RJT has Crit Chance ( 2) and Crit Damage (4)), or three 2-sets, all of them same (e.g. KRU has three Defense ( 2)). When I look at Krrsantan's info circle on the basic mod page, I can see he only has Defense ( 2) and Health ( 2) listed for his mod sets. This is probably what's leading to this behavior. I don't know of any other character that has two different 2-set mods recommended, so this nuance probably flew under EA's radar. (EDIT: Just noticed Aayla Secura has two Crit Chance ( 2) and a Potency ( 2) listed)

FYI, I just noticed this issue when I was searching for mods for him, and it was suggesting some Potency and Critical Damage mods from the store, which was odd given only Health and Defense are listed as recommended.
