ACLS, case III : mode 1 switch to mode 2

[IronStar95]

Hello,

I created a case III training mission to test the ACLS. It worked perfectly until a few days ago. Now, when I think I haven't changed anything, the ACLS switches to mode 2 by itself, which makes landing very difficult.

Why ?

Switches where?

Don't think our Hornet is even capable of showing anything but "MODE 1" on the ACL page.

And the ATC always says "fly MODE 2", just ignore it.
