I have the same issue. The issue exists on five separate companies and the "workarounds" are basically useless. I can't recreate a contractor if they are already attached to time entries and billing. The development of this portion of the product sucks. It has sucked for many years and does not get better. Definitely worth the $1,000 a year that is being paid to Intuit for a product that doesn't work for basic functionality (sending a stupid reminder).
