export skips content and shifts one column

Hi allaerd.
I hope you can help me.
As you can see in my screenshot, between comment_count and product_type something happens and export seems like skipping a column and shifting content of a column to the right. So, as you can see, “product_type” should be set to “simple” in X2 instead of Y2.
What causes this?
Hoping in your replying, many thanks in advance for your support.
