Issue of Automatic Change of Uppercased English Word to Lowercased One

Hi, I was wondering if you were also experiencing automatic change of an uppercased English word to lowercased one in the translation. Whenever I typed an uppercased English word, it automatically turned into a lowercased one if I progressed on typing further after touching the space bar. I guess there must be a way to solve the issue by changing the setup of SDL Trados 2017. If you can, please help me solve this headache. I'd appreciate it.
