Monacelli 2005 help -- blanchard kahn conditions

I’m trying to estimate Monacelli (2005), Monetary Policy in Low Pass-through Environment with a few modifications (Taylor rule). I keep getting Blanchard-Kahn indeterminacy unless I make foreign output exogenous. I’ve been struggling with this issue for days and would really appreciate it if someone could take a look and point me in the right direction. Thanks!

There are 4 eigenvalue(s) larger than 1 in modulus
for 5 forward-looking variable(s)

The rank conditions ISN’T verified!
