I use the shortcuts F4 to F8 to open Layout Presets 1 to 5.

There are the following bugs when calling these presets through shortcuts:

1- No blue box checked (if I click a layout preset with the mouse, the box is highlighted in blue)

2- Channels don't change the width (no memory of minimized width/maximized width of the channel)

3- Channels don't change the status of the panels (no memory of opened/closed panels of Settings/EQ/Dinamycs)

Layout presets works perfect when clicking mouse, but not with shortcuts.

* I'm using TotalMix FX 1.64 & MacOS Mojave 10.14.6
