API Changed after V44 to Read all MAC's only 96 are being genearted

We used to use https://core1.acme.com/ns-api/?object=mac&action=read&format=json to pull list of all MAC;s. We would typically get thousands of MAC's and now we are only seeing about 96 when posting the get.

Has anyone ran into this or have any ideas? I looked our the kb and tested other get commands and still its not pulling all MAC's. We use this to update our MAC list with one of our auto provisioning services.
