Using the e^(x) key changes to EXP(x) in CAS for me . WHY?

[trigamist]

I've noticed that my HP Prime likes to change functions from my preferred form of "e^(power)" to "EXP(power)". I do not know why this happens as it only occurs when my calculator is in CAS mode (regardless of app) and I cannot find a setting to alter this. I've seen youtube videos of others writing this out fine in CAS. Even clicking "Shift" -> "LN" will output as "exp()".

This makes reading functions/equations less pleasing to my eyes .

Help, please?

Ex.1 Should look like: x*e^x
Does look like: x*EXP(x)
Ex.2 sin(e^3)
sin(EXP(3))
