Selecting stuff doesn't select right away

Hey there.
Just switched to Cubase 9 Pro a while ago.

A lot of times when I’m gonna select for example a send bar in the mixer or an insert plugin, i have to click twice (or sometimes even three times). Instead of selecting the send bar or the plugin either nothing happens, or the little area around it is highlighted and THEN I can select the specific thing I want. Incredibly annoying since you do these operations hundreds of times per working hours. I like to keep things effective and without as many steps as possible to have a fast way from idea to doing.

Solutions? Anyone else experiencing this?
