[TYPO3-english] Formhandler localization problem. Typo3 6.1.5

[Andrei Shishkin]

Hello.
Have 3 languages, setup:

config {
   linkVars = L
   sys_language_uid = 0
   uniqueLinkVars = 1
   language = en
   locale_all = en_EN
   sys_language_overlay = 1
   sys_language_mode = ignore
   htmlTag_langKey = en-EN
}
[globalVar = GP:L=1]
config {
   sys_language_uid = 1
   language = id
   locale_all = id_ID
   htmlTag_langKey = id-ID
 }
[global]
[globalVar = GP:L=2]
config {
   sys_language_uid = 2
   language = ru
   locale_all = ru_RU
   htmlTag_langKey = ru-RU
}
[global]

Menus and content translating works good. 
Trying to use formhandler extention for organise contact form.  
Installing it like said in www.typo3-formhandler.com/documentation/articles-howtos/b/how-to-set-up-a-simple-form/ 
using xml langFile, with this sructure:

<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
<T3locallang>
<meta type="array">
  <description>Language labels for my form</description>
</meta>
<data type="array">
  <languageKey index="default" type="array">
    <label index="error_message_required">English</label>
  </languageKey>
  <languageKey index="id" type="array">
    <label index="error_message_required">Indonasian</label>
  </languageKey>
  <languageKey index="ru" type="array">
    <label index="error_message_required">Russian</label> 
  </languageKey>
</data>
</T3locallang>

As result -  default english version works, russian version - works. Indonesian - NO. It just do not whant to take translation from <languageKey index="id" type="array"> section. In the same time all site showing indonesian version of the site, but formhandler showing default version of lang, english. What can do to solve this problem? 

Thanks for looking.
