Future-dated inventory adjustments?
Hello all. We recently had some consultants "help" with our inventory woes, and I'm working to uncover all the things they screwed up. >:( I found adjustment entries on products that look like this (this is on the Inventory Center view of a particular product):

Dec 2018 PI refers to a physical inventory count that we did in December 2018, which resulted in a bunch of adjustments like this one. However, it appears this adjustment was incorrectly postdated for December 2019.
From this I infer that, effectively, the adjustment hasn't yet happened. My gut tells me this is very bad, as this same apparent mistake is repeated across many products. Am I right? If so, what's the best approach to correcting this? Thank you!
