Texte revert when pricing items

If i put a stack of 10 currency for 60c, it show good on tb but said 1 for 60c on web browser.

When i type on my stack of 10, 1/6c, it looks right on tb but said 1c for 6x of that currency.

I didnt find any way to fit my listing with tb and web browser, they do not say the same thing.

I tried 10/60. On tb looks good. On webbrowser my listed currency disapeared.
