Hello. I'm working over Tumblr automation template but i'm faced a problem. I can't change post type using zennoposter. Look at this

HTML or Markdown can't be selected in zennoposter browser. I want to know why this not work and is there any solution? I'm using version 5.10.4.0 (latest) not works on previous version also.

Here are tumblr test login details if someone wants to preview this issue
