When i update Coursepress PRO it overwrites my templates and my languages files

Hello when i update CoursePress to the newest version it ovewrites my template (Coursepress template) and my languages files (Portuguese)

I already solve the template problem making a copy of plugins/coursepress/themes/cousepress/ into my themes/cousepress-copy/ templates directory. I just want to know if this is the best practice or i can have problems with new updates.

About the translation it works if i re-upload the translation files, but i want to know if is there a way that i can keep my translation when i update the plugin?

i already tried to put the translation files into the themes/Coursepress-copy/languages/
but it doesnt seem to work
