Prices incl tax setting bug

I have an issue with the tax settings on my site.

The products (along with prices) has been imported from at Prestashop install into woocommerce. At the time of the import the “I want to enter prices incl. tax” was set to “No”. Now i would like to change the setting to “Yes” – making it possible to enter the full price of a product including tax. The tooltip for the setting claims that changing this setting will not affect existing products, however when i change the setting all prices on existing products are reduced.

I assume that this is not expected behavior, however I lack ideas on how to solve this issue.

Suggestions for a solution are much appreciated.
