Watched dates disappearing

[tylergfoster]

I'm currently in the process of updating my entire collection to have the price data in the right field. I used to have it in the comments but I'm moving it to the actual price field. To do this I've been going to pages of my collection, selecting all titles and hitting edit, but this has been deleting the watched dates from my discs. If I add them individually they return, but having corrected one at random and then doing the select all thing again, the date disappears on the edit screen featuring all the titles. Purchase dates are unaffected.
