Replacing colon with empty string

[Timu57]

Is there a reason why the colons in the label text are replaced with an empty string in line 152 by the getLabelText method?
I removed the replacing to test if it breaks something but everything worked fine.
I need to show a url, with https:// prefixed, to the user.

Thank you in advance

It removes an asterisk in case this has been added to the label to denote a required field.

I am unsure why the colon is there, this was added in v1.0.7 however I no longer remember the reason.
