translation is not applied

Hello,
I translated your plugin several weeks ago, but the translation has not been available (downloaded by wordpress itself) to my wordpress site (www.remarpro.com).
Then I looked at your plugin code and found the following:

Plugin slug: uber-nocaptcha-recaptcha
* Text Domain: uncr_translate

They are different, but I see that other plugins use the plugin slug for the text domain (i.e. they are same). I am not sure this is the cause why my translation hasn’t been downloaded, but I appreciate you check (try) other language translation than Japanese.
