We are having the same issue - we need to modify rates assigned to each entry along with changing billable status. I'm missing an entire day of work to deal with this as I'm unable to modify these entries and invoice, currently on hold with QB Time customer service after going in circles with QBO customer service... this platform is consistently failing customer needs, making nonsensical updates, and the responses reflect no familiarity with product function whatsoever. This issue will make QB unusable for us.
