WordPress is stripping the Alt tag’s quote marks from images where Alt is not set, but leaving the word ‘alt’ creating problems for ADA compliance

How do I get around this? For ADA compliance I specifically need alt="" on some of my images in a wordpress site, however wordpress is stripping the Alt tag’s quote marks from images where Alt is not set, and just leaving the word ‘alt’ without the quotation marks. How do I make sure the Alt tags are left intact with their quote marks? I just need it to say alt="" instead of alt. ! 😀
