Unfortunate that this is occurring on your site. While a product being placed in a subcategory is a characteristic needed for it to occur, there is more information needed. Specifically, this is expected to be a possible condition for a store having or trying to have more than one language.
Next, the concern being addressed by the messaging is that the product is not being placed in the same tree position across languages. I suspect such a situation may be "normal" to try to do, but things I have seen about the configuration of categories within the store is that there is category that has multiple language assignments and then product at the last category of a branch and no category is to have a product and category within it. With that set of "requirements", even if a store owner wants to display categories in groups more appropriate to one language than another, there are limitations applied (it seems) to prevent such.
Anyways, could you please identify how many languages you have in your store, then perhaps give (example) data from the header and first row of your import file? Exact data can be changed, but at least show format, sequence, that sort of thing. Then when there are multiple database languages, the thought/concern is with the field data being imported.

Thank you for your advice.
I turned off the second language. The file is importing correctly now.
Would you mind showing the first row of what the file looked like that was causing the issue? Generally speaking my intention was to allow Import to a multilingual database, though I wonder to what extent I limited such and furthermore to what extent that is expected or required. E.g., in language 1 a product is in cat1^cat1_1 in language 2 though in cat1^cat1_2 instead.
Reason I perceive the problem occurred is that in assignment or reassignment to another language is that if the category exists in both languages but is only referenced in the one then a search is not performed to push it to both languages. But, I await further information to try to resolve the issue identified.
