Duplicate Function Names

[NS@xxxxxxxxxx]

I thought you couldn't have two functions with the same name, but I
just noticed I have several Read Only functions with the same name,
but slightly different code.
All are Omega Research functions with the same Last Edit date.

Here is a list of the duplicates
Average
Highest
HighestBar
LinearRegAngle
LinearRegSlope
LinearRegValue
Lowest
LowestBar
Summation
Weighted Close

Here is the text of the two Highest functions to show the differences
Although the program seems to work OK with these duplicates my question is
Should I delete one of each of these? I don't want to give the program
any reason to slow down or get confused.
