Data Labels for Line & Clustered Column Chart

Hi,

I have a line and clustered column chart with data labels enabled for the columns , but they only appear outside of the bar. I would like to move them to the bottom or center of the bar so I can then enable the data labels for the line so they don't overlap. However when I select "Inside Center" or "Inside Base", they disappear. Does it have something to do with the size of the visual? It seems large enough to me .

Works when "Auto" or "Outside End" is selected for position:

Data labels disappear when "Inside Center" or "Inside Base" for position is selected:

Im not sure what other settings to adjust. Help would be appreciated!

Thanks
