i deleted all the licenses and re-activated the slf file.
All is imported ok, and under admin --> licenses i can see all my 9 licenses from the .slf file:
2016, 1 license xxx seats, 1 license xxx seats, 1 license xxxx seats
2017, 1 license xxx seats, 1 license xxx seats, 1 license xxxx seats
2018, 1 license xxx seats, 1 license xxx seats, 1 license xxxx seats
However license details in home still show "attention required", its shows the expiration date for the first years license, the slf file also have licenses for 2017 and 2018 will this be selected once the expiration date for the first year (first license) has past?
