Typograhpy issue on woo cart and checkout

Hi, first of all thanks for a great theme. Love it!
I have an issue with typography concerning only Woo cart and checkout pages.
Some texts are showing there with first letter uppercase. This is concerning product add-ons texts and texts defined in the products advanced tab. All other text is shown correctly.
Of course I have tried to switch in costumizer. Works fine on all other texts on cart and checkout, but not on the ones mentioned above.
Anyone else with this issue?
Please help! I love ocean wp and do not want to use any other theme…
