Hi, thanks for getting in touch!

This is expected behaviour. When you import into a matrix field, we have no way of matching the existing blocks with the data in your feed. This means that each time you import into a matrix field, the blocks that were there before are removed and new ones are created. If you only have data for one field in a matrix block (and you’re not using defaults), then the rest of the fields in that block will be empty.

I hope this clarifies things!
