Thread for requesting actor/guest nationalities approved

My first post here.  How do i add "Country" " Language", actor's name?  I am trying to add an entry but having a problem adding them since it is not on the drop list option.   There is a new Boy Love series from Myanmar i would like to add.   Here's the source:  https://gaydaytime.proboards.com/thread/2890/bagan-beginning-myanmar-burma
