Energy data download function won't span 2 months

I am trying to download data from the energy dashboard that spans 2 months. From april 24-may 25. The dashboard creats the graphs quickly but wont create the csv. file. The Download Data button just stays grey.
If i only want data for the current month, that downloads fine. Am i missing a setting?

UPDATE: if i simply select the same timeframe a month earlier or later the downloads work fine. The difference is there are no new sensors in those months that were added mid-period like these grey ones were. This might resolve itself next month.
