Traefik Ingressroute Certificate rotating issue

We are picking the certificate from akv and secret is created. Applied that secret onto ingressroute in tls.secretName.Then we restarted traefik pod and application deployment.After hitting the url of application it is showing new certificate for some time.again after few hours it is reverting back to old certificate.

below are versions:
k8’s: 1.33
traefik version: v3.1.4
installed through helm.

Any suggestions would be of great help!

Why use a 1 year old Traefik version?

Yeah.. Any suggestions to migrate to new version or stable release.
