Hi,

1. when you click on the small map icon on the low right, you can see that Openstreet maps + Carto positron are both selected. I guess here should be only Carto maps selected(before there were open street maps) and shown on the map as default. Otherwise blicking stopped, nice job.
2. Filter on dashboard is still not functioning, we leave it this way for now?
3. Run initial load and check timeseries slider, it shows year for start and end date and also for slider dates.
4. Filtering date on dashboard doesn't work, it worked before?
