Static routes exported shown under Internal routes in ISIS

Hi bro.

I have a topology like that

MX-01-LG-01--------------------MX-01-LG-02

From LG-01, I export static routes into ISIS

root@M5X# show logical-systems PE-02 policy-options
policy-statement FROM-STATIC {
term 1A {
from {
protocol static;
route-filter 190.90.90.0/28 exact;
}
then accept;
}
}

---But when I check route at LG-01, it appears like Int, not EXT

show isis route logical-system PE-01

190.90.90.0/28 1 1802 10 int lt-1/0/10.1 IPV4 M5X-PE-02
