Inconsistent data points: Watchlist missing total returns for certain years, but those same years' data does show up under yearly periodic total return graph/table view

I created a watchlist with a number of stock tickers. Column selected include yearly total return figures. For some stocks, total return columns for certain years show up on the watchlist as blanks. However, when looking at the same tickers individually through a graph view which includes yearly periodic total return as one of the parameters, yearly total return figures are shown for those same years. It will be good if the watchlist (and its associated download) can be corrected to reflect the same year-wise total return figures instead of showing those years as missing. Attached screenshots show one ticker as an example. I'm also attached a screenshot of the download containing data for all the selected tickers which have certain years' data missing (highlighted in yellow).
