All brokers do this because the each option leg is a separate trade and one executes in response to the other, and can happen on different days. It's the same as owning stock and having ITM options that will close that equity position, but the totals will be skewed until then. Broker UIs can be made clearer but these are basic fundamentals.

If anything, it highlights the fact that these people should not be trading in the first place if they don't understand their own positions, and brokers need a much stricter gate before allowing them access.
