I'm trying to remove the digits in my document that has been tokenized.
However, using the erasePunctuation function, I didn't see any changes (no digits were removed) to the updated document. I've checked the type, and the tokenizer does recognize these tokens as digits. Please help. Thanks.

erasePunctuation still only erases punctuation, not numbers. The 'digits' specification tells it what type of token to remove punctuation from. See the description here.
You could try to remove digits using the following.
tkD = tokenDetails(cleanDoc);
cleanDoc = removeWords(cleanDoc,tkD{tkD.Type=="digits"});
