i fixed it manually. i noticed my installation has a userDefinedLang folder which contains the default Markup language settings in an XML file, but I also have a separate userDefinedLang XML file which contains my customized languages.
once i fixed it i can see the settings in the XML file i also made a copy on network drive and can see the same formatting in that XML as well.
not sure how i lost the other one but at least i know how to troubleshoot if it happens again.
thanks for the attention
