Welcome to Q&A forum ~
Your issue is related to License, which is not supported on Q&A forum at currently.
To help you better, I would suggest you contact VLSC to have a confirm.
Can you find the "Licensed Product" name for 3 Effective Quantity?
Via searching online, the Effective Quantity is the number of licenses you have paid for. Please also check types of 3 licenses (Volume Licensing Key, KMS, and MAK).
In my opinion, the Effective Quantity does not determine the MAK activation number.
If you have Office license with using MAK activation, each MAK has a predetermined number of allowed activations, based on your Volume Licensing agreement.
Besides, the number of activations available for a product may not always match the number of licenses purchased. Usually you will receive a higher number of activations in case you need to reinstall and activate some of your products.
