Data Types and StockHistory Missing in Beta

I recently upgraded to latest beta release update (Version 2502 - Build 18502.20000) and noticed that Data Types have now disappeared from the Data Ribbon in Excel. STOCKHISTORY formula still shows up as a usable formula, but when I enter the fields, I now get a #CONNECTION error. Has Stocks as a data type now been removed from the newest versions of Beta or is this a bug? Anyone else experience the problem?
