#146 1 SQLSTATE [42S02]: Base table or view not found: 1146 Table core_store does not exist

[Leo]

Hello
I am using the magento version 2.2.3
I installed magmi via this link (the file) zip:
https://github.com/macopedia/magmi-m2/tree/magento2
but I have an error message:
SKU OR1100000000 - 1 SQLSTATE [42S02]: Base table or view not found: 1146 Table xxxxx_core_store' does not exist -

and actually when I look in the db, the "core_store" table does not exist but "store" exists
Thank you
