border-right-width

if o open table properties window on a table, in styles apear: border-right- width: 700px

there is a space between "right- width".
i think that mus be a wrong interpretacion of the ckeditor.
in the html code its written correctly.

so if a want to save, its not posible, because i get an error message.
i have to correct manualy border-right- width to border-right-width
and it works.

is there any way how i can correct this o a fix?

thanks and regards from madrid
