Why does IBKR list withholding tax for 2 countries, one with a positive and one with a negative sign?

For Airbus dividends, I see withholding tax for both FR and NL listed in my reports, but for NL it is listed as a negative value (deduction - as expected), and for FR it is listed as a positvie value. It looks like this:

2024-04-18 | AIR cash dividend 1.00 per share - FR tax | 5.75 EUR
2024-04-18 | AIR cash dividend 1.00 per share - NL tax | -3.85 EUR

It seems that only NL withholding tax is what I should report for my tax purposes, but I'm not sure what a positive withholding tax entry could mean. What is the correct way to read this?

This is confusing to me because for e.g. US stocks, withholding tax is always listed as a negative value only.
