Here is all log related to region 127106. After splitting, there are 3 replicas located in store 4, 8, and 6. Then PD adds a scatter operator which adds two more replicas on store 5 and 10. But there is no more step. After a while, the rule checker found there are 5 replicas for region 127106 and it exceeds the expected replica number. So it removes the newly added replicas located in store 5, 10.

What version of PD are you using (pd-server -V)?

v6.5 but might affect many versions after v6.1, not sure for now.
