Extract All Occurrences array issue?

I am extracting all occurrences of a particular variableX. I am using the 'Alphabet character' as my criteria.
The array contains the following [,AL,AX,LC,].

Why are the first and last values extracted? It means that variableX_1 and variableX_5 contain null values.

the * is zero or more characters, so zero alphas will match, see my screenshot from regex101.com

Because they match a pattern in the response, what does the response and regex look like?

How can the first and last array values match the pattern in the response if is is looking for an alphabetical character?

The regex is \n<option value="([a-zA-Z]*?)"
