The data you are seeing is accurate, but perhaps not what you are expecting. The 194 is the aggregated value for that measure, on the level of the dimensions that you have on the Columns and Color shelves on that sheet.
Can you clarify what number exactly you are expecting to see? If it's the total for that stacked bar, have a look at the following article: http://onlinehelp.tableau.com/current/pro/desktop/en-us/help.html#buildexamples_bar.html
If you want to show the total in the tooltip as well, I'd suggest using a Level of Detail calculation, or a Table calculation to compute the total over the dimension you have on the Color shelf. Let us know if you need more clarification here.
