ANA 2 - pre set bundle error

Hi Guys, I have recently purchased ANA 2 + Ultimate Presets Bundle (6 Preset Packs). All downloaded fine but having problems using downloading the following preset packs one the bundle:

vol-2-future-bass
ana-2-presets-vol-1-pop-and-future-house

I am using macOS Catalina version 10.15.7

when downloading I get the following error message

“ANA 2 Presets Vol 2 - Future Bass.pkg” cannot be opened because it is from an unidentified developer.

I am selecting the correct Mac file once downloaded

Your help would be much appreciated!

Thanks

John
