Keyboard not popping up in Steam.

When I go into Steam and tap on the search bar, the keyboard pops up then glitches away. Only happening in Steam. 
May be something simple that I’m missing.

Still really new to all this and just trying to love it. gaming.lenovo.com/.../73741449484_5F005F00_9EA95A78_2D00_7C6A_2D00_4006_2D00_A2CA_2D00_208B9F82AC75.MOV
