RemoveRule rpc API problem

[mrbereg]

Hello! I try to delete routing rule using rpc API command RemoveRule. I faced a problem. This command successfully deletes routing rules by tag loaded during xray startup from config.json but it doesn't delete rules added via rpc API command AddRule in runtime. Is it possible? Or I should rewrite all routing section with shouldAppend=False arg?

import grpc

from app.router.command import command_pb2 as router_pb2
from app.router.command import command_pb2_grpc as router_grpc

def remove_rule(server_addr: str, rule_tag: str):
    channel = grpc.insecure_channel(server_addr)
    stub = router_grpc.RoutingServiceStub(channel)
    req = router_pb2.RemoveRuleRequest(ruleTag=rule_tag)
    return stub.RemoveRule(req);

import grpc

from app.router.command import command_pb2 as router_pb2
from app.router.command import command_pb2_grpc as router_grpc
from app.router import config_pb2
from common.serial import typed_message_pb2

def _pack_typed(msg) -> typed_message_pb2.TypedMessage:
    return typed_message_pb2.TypedMessage(type=msg.DESCRIPTOR.full_name,value=msg.SerializeToString())

def add_block_rule(server_addr: str):
    rr = config_pb2.RoutingRule(tag="blocked", rule_tag="TESTBLOCK")
    rr.domain.extend([config_pb2.Domain(type=config_pb2.Domain.Type.Domain, value="example.com")])
    cfg = config_pb2.Config(rule=[rr])
    typed = _pack_typed(cfg)
    channel = grpc.insecure_channel(server_addr)
    stub = router_grpc.RoutingServiceStub(channel)
    return stub.AddRule(router_pb2.AddRuleRequest(config=typed, shouldAppend=True))
