Joomla Real Estate

I ask you for Help with editing the File "RealEstateManager.xml".
In your description in "How to add a new Language to Real Estate Manager" I Understand the first point, but I do not Understand point 2 and point 3:
Text of "How to add a new Language to Real Estate Manager":

===============================================

You can either do the operations on the component archive and then rezip and install, or edit the necessary files in place inside an existing installation.
1. Place your language file inside the directory
/components/com_real estate manager/lang/ using an FTP client or similar (if you are on a shared hosting account, please use internal Joomla FTP or QuiXplorer or similar to preserve the file ownership).
2. In the file RealEstateManager.xml in the directory /administrator/components/com_realestatemanager/ add the language entry for your language. This goes right after the entry language/english.php.
So if you use for example Dutch and Spanish on your site you would add those, like this:
lang/english.php
lang/dutch.php
lang/spanish.php
3. To ensure the languages you use are visible inside the dropdown boxes in the administration part for selecting, you will need to add the language entries to every language file in use in your installation. In each language file, find the part marked //Languages and add your language there. Example:
//Languages
DEFINE('_RealEstateManager_LANGUAGE_NOT_USED', 'Not specified';
DEFINE('_RealEstateManager_LANGUAGE_ENG', 'English';
DEFINE('_RealEstateManager_LANGUAGE_DUT', 'Dutch';
DEFINE('_RealEstateManager_LANGUAGE_GER', 'German';
DEFINE('_RealEstateManager_LANGUAGE_FRE', 'French';
DEFINE('_RealEstateManager_LANGUAGE_ITA', 'Italian';
DEFINE('_RealEstateManager_LANGUAGE_SPA', 'Spanish';
etc.
Save each file. Remember to translate the entries according to the language file you are editing. That's it, you're done!

Hello,

reread article How to add a new language to Real Estate manager ordasoft.com/News/Real-Estate-Manager-Do...-estate-manager.html now, we edit point 2 and remove point 3

Thanks,
OrdaSoft team

Thank you.
Now it is under Article much easier! Thank You!
I added to my Language Directory File Czech.php. I switched from Joomla English to Czech Language. When you open the Language Manager, Real Estate always turned off. Setting the Czech Language did not hold. After about 10 attempts remained set Czech Language. I do not know why?

Another Problem is when I do anyLinguistic Change in Language Manager. After saving the changes are set each Brazilian Language. How to fix this Problem please?

I need have only my Czech Language. It is possible to delete the other Languages​​?
Thank You very much!
