Problem with importing combinations by built-in importer

[staszewski]

I ran into a problem updating combinations (stock, price effect) in prestashop 1.7.7.1. When I try to import a csv file, I get the following message:

    Errors have occurred:
    The Attribute-> position property is not valid

I export data from the store using the MYPRESTA plugin. The value of the Post-Export attribute column looks like this:

    Size:radio: 0

In the presta back office, the "Size" attribute has an id of 1 and 1 item on the list.

I tried to change the attribute field to:

    Size:Radio: 1

But this results in an import attempt with the following message:

    Errors have occurred:
    The Attribute-> position property is not valid

Also the Value look this way:

     "l (55 - 17 - 150):142"

Any ideas what this might be about?
