Hi, for the Class:Swordsman issue, you need to add a space onto the end of the Class Text parameter under Text Options in the plugin parameters. I do not want to hard code a space after those parameters because other languages do not always use spaces to separate strings of text like that, and default parameters do not support spaces at the end of the parameters so it needs to be manually added by the user.
For the face appearing underneath the other texts, this is just how the face display interacts with certain other display options, such as the headers and the stat display. It is like this because it would look a bit weird to have only the first stat row offset from the rest due to the face graphic, whereas single-line pieces of info look more natural when they are offset like that. You can also add blank lines if you don't have enough info you want to display next to the face image.
For the face not showing until refreshing the window, actor faces are typically loaded already because they are shown in the main menu, in battle, or in text windows (or lots of other areas). However I do see that it is possible they won't always be loaded, I can fix this in the next update for the encyclopedia to wait for them to load if not already loaded, thanks for the bug report.
