I worked KB4REC and W0JRJ as new stations and state disappeared on both. I then re-worked W3CVD and WB0N. W3CVD had been previously worked on 15 Nov 2018. WB0N was worked on 15 Aug 2019. Both showed their state but after I worked them they both did not.
Hope that helps. I did update the callsign database to 2020.03.19 before operating today. Let me know if I can do anything else.
