SL 2: triggers - jump to scene

In my project i have scene 1 = basic
Scene 2 is for every location and scene 3-10 are specific scenes for specific locations.

In scene 1 i have a slide which has 2 buttons for north and south (a - b) for selection. Both go to Layers which also have buttons for regions (say c-h and i-p). That buttons go to another set of layers for locations in that regions.

In that locations layer i have (for example) location (button) aa, bb and cc

I have made variables (aa = false and bb = false).

When clicking on button aa i have made a trigger:
Action: adjust variable
Variable aa or bb
operation = assignment
Value: Value / true
When: user clicks
Object: button aa (or button bb)

Both buttons have the trigger to jump to scene 2.

So far so good. But now i want button aa to jump to scene 10 slide 1 and button bb to jump to scene 3 and then to scene 10 slide 1.

The last slide of scene 2 has a button: next. On this button i made a trigger:

Action: Jump to scene 3
When: user clicks
Object Button next
On condition: list: variable, if: bb , Operation: ==is equal to, Type: value, Value: true

 I also made a trigger on that button:
Action: Jump to scene 10 slide 1
When: user clicks
Object Button next
On condition: list: variable, if: aa , Operation: ==is equal to, Type: value, Value: true

In scene 3 on the last slide i also made a next button with the following trigger:
Action: Jump to scene 10 slide 1
When: user clicks
Object Button next
On condition: list: variable, if: bb , Operation: ==is equal to, Type: value, Value: true

What happens is:
Clicking on button bb sends me to scene 2, scene 3 and scene 10 slide 1. BUT button aa gives the same route while i want it directly from scene 2 to scene 10 slide 1.

What did i do wrong?

Thanks in advance and happy holidays!.
