This is the reason Heck gave in the 5/15/2020 news release:
"Many of the financial reporting issues center on A.S.C. Rule 606 which deals with revenue recognition. The company had operated and recorded revenues for the better part of a year and a half with the understanding that it was in compliance with Rule 606. While this is fixable, this has been a time-consuming, monumental undertaking as we have had to resurrect project start dates, completion dates and payments for every deal that we have done for almost two years."
