If you renew your certificate now (or simply re-download the existing certificate) it should come with the chain that you expect.
That said, this is related to our announcement from July: the short chain you got this time will become the default in Feb 2024, and and longer compatibility chain you expected will go away entirely in June 2024. If you truly need the longer chain to support users on Android 7.0 or below, then you will need to configure your client to request the alternate chain before Feb, and you will need to find some other solution (e.g. encouraging your users to upgrade) before June.
