That sounds like you are agreeing with the post you are replying to: the IRS is trying very hard to stick to their rules. You have a deduction that neither you nor the IRS have paperwork for (since the fund is not acknowledging it as a covered expense), so they are following the rules. I can understand how you are frustrated about the situation, but this does not seem to me to be random behavior, but rather straightforward rule following.
