Oh, maybe you can edit your post and take away your email, because I think this forum has some bots visiting sometimes...
(I have copied it to invite you to the translation though...)
I think after 2020-06 these expressions have been regenerated during a big overhaul of the software and added to the database. Those 'new' expressions were not translated. It is a problem in the translation platform that we are aware of.
So you can help with the translation; I saw there is a lot of work still with Armenian.
To solve the template problem for now copy the template you use (like MW-Schedule-1.htm) to a place outside the template folder (you have no permissions to change anything withint). Open the template with a good editor (Brackets, Code Writer, Notepad++, but not Word or a browser)
Find the placeholders that retrieve the localised expressions !PRAYER!, !SONG!, !GM! !FM! !CHAIRMAN! !READER! etc (I think there are about 12 - 15. Take these placeholders out (including the exlamation mark) and replace them by the actual expression in Armenian you need.
Save the changes and give the modified template a recognisable name, like MW-Schedule_Arm-1 or so, as long as the 'MW-' bit stays intact. Then move the modified template back to the template folder. It is about 5 minutes work.
