Merge multiple excel files into sharepoint folder

Hello, I have 4 folders created with excel workbooks that follow the same column-level scheme.

When I try to compile files using the binary option, a table is created that only contains data from Ecuador but the other plants are missing.

Alklguien knows how I can solve this problem? or something I'm doing wrong? xq I should generate a table with all countries

The steps I do is go to content, merge taking first file.
