Inconsistent name format on visa documents

Hi,

I was wondering if someone could tell me how concerned i should be or if there is anything i can do. I have recently submitted my visa application via bls Manchester UK, once i got home and checked over my documents again i realised some issues.

To start with i should say the names are all the same, however they don't all match my passport. There are two documents with issues: firstly being my acceptance letter from the university I plan to study at, they have hyphenated what shows on my passport as like a second part of my first name to my second name. so the format on my passport is

first name: x y, second name z.

but the acceptance letter says:

first name: x, second name y-z.

Additionally my GHIC has moved y to be in my first name so it reads

first name: x, second name: y z

I get this is a tiny thing but I've never been through this process before and I'm not sure how its going to be seen or if it will make my visa get rejected. If anyone has any experience or thoughts on if this could go wrong/ what i could do could you please lmk
