Text macro strips out numbers

I just want a simple text macro to type out my email address.
It's of the format "aaa4bbb"
but the macro returns

Please advise.

Create a macro which does 'Insert Text by Typing' and enter your email address in the box

change ⌥ E to whatever you want

Since I wrote my question post, I've noticed another odd thing... If I create a text macro to type the phrase, "zxcvb" and I make the hot key option-z, the text returned is "xcvb", stripping out the "z" ; if I change the hotkey to option-b, the text returned is "zxcv"

Is there an obvious explanation for this behavior, strippings out the letter used in the hot key?
