Lifecycle manager not showing PERC firmware update

I have a Dell PowerEdge T150 with a PERC H745 fitted and the lifecycle manager (LM) correctly shows the current firmware version as 51.13.2-3714, however, it's not offering the latest 51.16.0-4076 via the "Dell Website" option.

The PERC H745 (405-AAWE) is sold as compatible with a T150: https://www.dell.com/en-uk/shop/dell-perc-h745-controller-front/apd/405-aawe/storage-drives-media

I've downloaded the latest catalog.gz from: https://www.dell.com/support/kbdoc/en-ie/000132986/dell-emc-catalog-links-for-poweredge-servers

It' mentions both the H745 update file (SAS-RAID_Firmware_F3J22_WN64_51.16.0-4076_A16.EXE) and strings stating "This release updates the firmware residing on PERC H740P, H840, and H745 controllers to package 51.16.0-4076".

Is this an error in the catalog and if so, please can it be corrected to offer the update for my system please.

Obviously I can apply the update manually but I'd rather the LM worked correctly given this appears to be a supported configuration.

Couple of images showing the current FW being identified but no update being offered:
