I explained the Character Profile 苦手なもの thing before, back when Maid-san was introduced. I'll repeat it here once again because of the "not good with" part I added.
苦手なもの
nigate na mono can explicitly mean "dislikes," as in with Hineri's profile (
Ch. 38) because we know she just hates those types of people.
It can also mean things that "one isn't good at" or things that "isn't one's cup of tea," as it possibly is in Mika-sensei and Maid-san (
Ch. 41)'s profiles. This could apply to Emily's too (
Ch. 29).
Now, without further characterization in the manga, we don't know which one it is exactly. I don't want to misrepresent them, so... here we are.
With that said, let me know of any errors and points of improvement. Thanks as always
