Issue solution
(If you have the issue from the title, try to disable new designer. Also Populate a microsoft word template it's a premium resource)
I am trying to create a flow where it takes the values of a excel table and use it on a word template.

Also, after correcting the main issue here, it's possible to create a file with this template as the next step? If so, I can point to a folder that may not exist yet? (it should create a folde for each year, and then for each month and create the file in the said folder. But if the folder already exists, it should just create inside the existent folder)
