Garmin Express keeps insisting I need Map Updates, then fails to install

Garmin Express tells me I need to install map updates for

Routable Cycle Map of Australia and New Zealand 2024.10

TopoActive Africa 2023.0

Routable Cycle map of Middle East & Central Asia 3023.0

TopoActive Powersports Middle East 2023.0

Routable Cycle Map of Africa 2024.10

If I click on the Install button, Express says it is preparing, then fails with "There was an error installing the update".

I unplug my Edge540 , and plug it in again, it syncs and tells me I'm up to date!!

If I "Manage maps", there is only the Australia and New Zealand map present and it version 2024.10, and doesn't need updating, which is fine, I'm in Australia. If I try to add the Afica and Asia maps to satisfy the Update notice, there isn't room on my Edge540 to accomodate any more than 1 of the supposedly required updates.

How do I make Express stop wanting to update maps I don't have, dont want and don't need?
