Schedule issue

Not sure if anyone has noticed this or having the same issue.  My charters change every day so that means I am activating and deactivating them everyday.  Well, when I go to edit a schedule the system swithces the aircraft on me for some reason, in particular the Beriev I am using.  It seems to only switch this one for some reason, I have two and it defaults to the 243 reg number…I am really having to keep an eye now when editing cause of this.

I’ll test this now
