[Bug report] Source based games keep adding US keyboard layout

Hello! This issue has been reported long time ago but its still present and not resolved.===Whenever i start a source based game it adds US keyboard layout that is only seen in language bar and not in region and language settings in control panel.I think it started happening when i reinstalled l4d2 and now it happens also with tf2, portal2, hl2ep2 and maybe all source based games.To remove it i first have to add US keyboard layout and then remove it. I have only my local language as input in "region and language" and location set to united kingdom since i don`t want programs in my local language on windows 7 64bit.It is very frustrating since it keeps changing the layout at random if i don`t remove it.===> Windows 8 and 8.1 both have this bug
