Address Record vs. Other Addresses Records

Where can i find the documentation about the different record types in an .eth Domain?

E.g. what will happen if I define an Eth Adress in the Address record and define an other Eth Address under “Other Address ETH” ?

Example config with redacted Addresses:

https://docs.ens.domains/contract-api-reference/publicresolver has all the detail.

With regards to your screenshot, would that still happen even when you refresh your page? I tried by myself and it happened because the change on OTHER ADDRESS did not refresh the change on ADDRESS until you refresh the page.
