SuiteCRM 8.2 Undefined label in Import Email

Hello, I have just update from 8.1.3 to 8.2 and when I try to import an email the buttons show UNDEFINED labels (I didn’t see in other modules).

Actions before write this post:

Set permissions correctly.
Check .htaccess is ok (/public)
Go to Admin and Repair.

Anyone with this issue?

Thank you.

And this is the browser log content:

Possible solution:

I access .htaccess and notice this two lines that I didn’t remember:

RewriteRule ^cache/jsLanguage/(……).js$ index.php?entryPoint=jslang&modulename=app_strings&lang=$1 [L,QSA]
RewriteRule ^cache/jsLanguage/(\w*)/(…
…).js$ index.php?entryPoint=jslang&modulename=$1&lang=$2 [L,QSA]

I delete this two lines and now I can see all the buttons. I don’t know if could be any collateral unexpected behavior.

Thanks.
