Cursor move to the left when start a recording

Hi,
i’m really a newbe in cubase.

I recently upgraded from cubase elements 8 to the last version 9.
There is a thing that is driving me crazy, i don’t know if this is an issue or simply there is a setting to do.

My problem is on the recording of midi tracks, with pre-count activated.

Before pressing “", i set the cursor position to the left locator, then when i start the recording by pressing "”, in the pre-count phase, the cursor move apparently random to the left of the initial position, starting record from a wrong position.

Can anyone help me?

Forgive me, i miss important information.
I’m using Cubase Elements 9 on a Mac with the last version of Mac OSX Sierra.
