No trials available for end of 2017 and 2018


First off, thanks for making all this great data available!

I have ran into an issue while looking at how the number of registered trials changes year-of-year for Psoriatic Arthritis. The graph below exposed something strange to me.


The big drop off for 2017 obviously seems incorrect so I did a little bit of digging. It seems as if there is no clinical trial data available for mid 2017 and 2018. Not just for Psoriatic Arthritis, for any condition I search for.
Is there something I am missing? All the data has been pulled programmatically via the public API. I have noticed that there was a data dump as recently as 6 months ago (04-01-2018), but they stop there.

Please let me know if I can clarify anything.
