CitriX IME is for unicode language (China-Korea-Japan), put Citrix IME at first place to avoid this issue.
This is related to IME sync, generally, after selecting "loadl IME", and end user clicks "Ctrl + shift", local IME and server IME will be switched, but some times it does not. For example, manually switched by mouse or pull down Ctrl key not pull up, local IME will switch, server will not. so, in order to make sure local IME to take affect, configure Citrix IME at first place in server.
