First note: Data issues. These buildings have explicit end dates of 2018-11-01 Therefore it is correct that they vanish in 2019. But shouldn't they persist through 2018?
Also, notice the orange features in the map. These all have a blank starting date, and an end date of 2018-11-10 We never did define the expected behavior for items which have a start and no end, or an end but no start. Maybe best to treat "" as the beginning/end of time, e.g. "prehistory through 1923" or "since 1776 through present date"
[x] Adjust filters to handle "" values as being beginning/end of time.
[x] Check filter logic re 2018-11-01 not fitting a year selection of 2011
49a3867 Filtering adjusted, so "" values are start/end of time ("prehistory", "current date and expected future")
This brings in several features which have a blank start date, and therefore had previously been missed:
Of course, this also means that these features are now displayed back into prehistory, such as in this screenshot from the year 100 CE:
5bfbce6 adjusts the filtering logic to include features which started/ended within the selected calendar year. Thus, those buildings in NYC will show when 2018 is selected, as they did have a presence during some part of 2018.
Could be a data issue. I'll fix any underlying data. Would be better if we could figure out an approach / wildcard for "current day / present"

May be a data issue, may be a computer bug, may be a hole in our whole logic for how to think of date filtering. Figure out what, so we can plan next steps.
