I have this issue which happens every now and then.  Its really not that often but it does ocurr maybe 2x a year or so.  If I go to the Inventory module and look at Master Data > Products and pick a product and then click on Price History it will take me to the price history card and its actually another product!

Lets say I enter a product's card and see the cost is 51.35 (we use average cost method) and I want to see the history of what price has been, I see that the prices are around 1,300 or 1,700 or 1,500.  And then I look at the product name and its actually a different product that the link took me to.  In other words instead of going to the price history of Product A which i wanted to see, the Price history link took me to the price card of a different product.

But then it doesnt happen after a while all is well.  It only happens when I go to Inventory > Master Data > Products.  It doesnt happen when i go to Sales module or Purchase module and enter the product there.
