I just tried to reproduce that problem with Ranorex 2.3.4, but the capital key did work just normal there. Could you post the recording or/and the code generated for it?
You can also try to remove the "{Capital}"; an upper-case letter in a key sequence will automatically be replayed as an upper-case key stroke (i.e. a key stroke with shift hold down). Actually, even if caps are locked, Ranorex will try to unlock caps when there are lower-case letters in a key sequence. To make Ranorex consider the current caps lock state, you have to use individual keyboard actions or escape every single letter in a key sequence, e.g. "A" -> "{Akey}". See the documentation for the corresponding Keyboard API method:
