Translation wont shows up

I already change some of my translation but it wont change. What happened?

I already run trytond-admin -c trytond.conf -d databaseme --all -l mycodelang

Please explain what you did exactly.

I edited the PO file and I run this trytond-admin -c trytond.conf -d my_database --all mylangcode -l, some of the field are changed but some don’t what happened?

This command line can not work. The language code must come after the -l option.

It is not possible to know as you do not give precise detail of what is happening.
