labels not working in timeseries

[Simoliv]

Version: Latest I guess, installed from pypi, redis is docker container, also latest

Platform: Ubuntu 22.04

Description:

I do not get any labels, no matter what I try. I tried from the documentation:

import redis

r = redis.Redis(host='localhost', port=6379, db=0)
ts = r.ts()

print(r.ping())

try:
    r.execute_command('TS.CREATE', 'ts_key', labels={"label1": 1, "label2": 2}, duplicate_policy="LAST")
    print("created")
except redis.exceptions.ResponseError as e:
    # Ignore error if the timeseries already exists
    if "already exists" not in str(e):
        raise

#print(ts.add("ts_key", 1657265437756, 1, duplicate_policy="LAST"))
#print(ts.add("ts_key", "1657265437757", 2, duplicate_policy="LAST"))

#print(ts.add("ts_key", 1657265437754, 5, labels={"label1": 1, "label2": 2}, duplicate_policy="LAST"))
#print(ts.add("ts_key", 1657265437759, 17, labels={"label1": 3, "label2": 4}, duplicate_policy="LAST"))

print(r.execute_command('TS.ADD', 'ts_key', 1657265437756, 1, "LABELS", "label1", 1, "label2", 2, "DUPLICATE_POLICY", "LAST"))
print(r.execute_command('TS.ADD', 'ts_key', 1657265437757, 2, "LABELS", "label1", 1, "label2", 2, "DUPLICATE_POLICY", "LAST"))
print(r.execute_command('TS.ADD', 'ts_key', 1657265437754, 5, "LABELS", "label1", 1, "label2", 2, "DUPLICATE_POLICY", "LAST"))
print(r.execute_command('TS.ADD', 'ts_key', 1657265437759, 17, "LABELS", "label1", 3, "label2", 4, "DUPLICATE_POLICY", "LAST"))

print(ts.range("ts_key", "-", "+"))
print(ts.mget(["label1=1"], with_labels=True))
print(ts.mget(["label1=1"])) 

results in

No labels. Is it a problem or am I doing anything wrong ?
