Similar issue here. The projects summary landing page and individual project's overview page used to show all correct values and now suddenly none of the costs are showing up making all the projects at 100% profit margin (only if they were true)

The QB online call was absolute disaster. The rep referred to this link and said that the only way to fix it was to delete over 1000 transaction i have over multiple projects, recreate them (invoices, bills etc.) and do a bank reconciliation again. JUST NOT AN ACCEPTABLE SOLUTION! I waste over 7 days of my time for something QB software is messing up? She refused to escalate this as technically there is a solution. The counter solution is for me to take my business to someone else. She gave me number to reach out 1-877-683-3280 which is for sales and does not help me escalate the issue. 

Absolutely unacceptable solution to delete all transaction are recreate them. If a rep is reading this - my case ID is [removed]. I'm sorry to vomit out on this thread but truly frustrated at the level of support. How do you even escalate your issue when rep deliberately misdirects you?
