Seeing old Upload CSV prompt?

Hi there,

I’m unable to update my products’ prices with a modified inventory .CSV as I am seeing this prompt:

Instead of this one:

Import error .txt file seems to support the apparent inability to merge and update existing products:

CSV was directly exported from the Products page under Ecommerce, and the prices were overwritten by a formula in Excel. The sheet was then exported directly as a .CSV. No additional modifying or formatting was performed in addition to the above-mentioned steps.

My products have variants. Maybe this is causing the issue?

Thanks,
Nathan

Any ideas? Is this a bug?
