Renew vault token

Question

I created vault token with the following settings:

vault write sys/auth/token/tune max_lease_ttl=9000h
vault write sys/auth/token/tune default_lease_ttl=9000h
vault token create -policy=spring_cloud

I'm trying to renew vault token with the following command

vault token renew -increment=9000h

And got the following warning:

* TTL of "9000h" exceeded the effective max_ttl of "4072h45m26s"; TTL value
  is capped accordingly

As i understand, the result must be the following: increment 9000h starts from the last_renewal date(2023-12-01T15:11:51.655977681Z), so expire_time and ttl must increase. Instead of this, we have expire_time which is not increasing = it's always 9000h from the issue_time date. And ttl also doesn't increase. Only decreasing. Vault version: v1.10.3
