IAS query returns GROUP_OUT_OF_DATE

Hi there, I'm currently using a NUC for some SGX related development work running the latest firmware that is available, details as follows:
> BaseBoard Manufacturer:"Intel Corporation"
> Bios Mode:"UEFI"
> Bios Version/Date:"BECFL357.86A.0081.2020.0504.1834,05/04/2020"
> Platform Role:"Linux nuc 4.15.0-106-generic #107-Ubuntu SMP Thu Jun 4 11:27:52 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux"
> Processor:"Intel(R) Core(TM) i7-8559U CPU @ 2.70GHz"
> SMBIOS Version:"3.2.1"
> System Manufacturer:"Intel(R) Client Systems"
> System Model:"NUC8i7BEH"

CPUINFO:
> vendor_id : GenuineIntel
> cpu family : 6
> model : 142
> model name : Intel(R) Core(TM) i7-8559U CPU @ 2.70GHz
> stepping : 10
> microcode : 0xd6

Performing a remote attestation with IAS results in a GROUP_OUT_OF_DATE response with the following advisories: ["INTEL-SA-00161", "INTEL-SA-00219", "INTEL-SA-00289", "INTEL-SA-00320,INTEL-SA-00329"].

Calling sgx_report_attestation_status results in the following:
> DEBUG] sgx: SGX_ERROR_UPDATE_NEEDED
> [DEBUG] ucodeUpdate: 1
> [DEBUG] csmeFwUpdate: 0
> [DEBUG] pswUpdate: 0

Downloaded the latest ucode file from https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files but it seems like I'm already running the latest ucode version.
> iucode_tool -S -l 06-8e-0a
> iucode_tool: system has processor(s) with signature 0x000806ea

> 001/001: sig 0x000806ea, pf_mask 0xc0, 2020-04-27, rev 0x00d6, size 103424

Any suggestions on what might be the problem?
