Blinking text in Libreoffice Version: Writer not fixed by unchecking blinking box.

i have continuous blinking text in my .rtf (Libreoffice Version, regardless of attempting to address the issue via format>character>font effects>blinking & unchecking the blinking box, this allows for a temporary fix but when doc is saved & reopened blinking reappears, is there a permanent fix to this annoying issue once and for all. any help & advice is most appreciated. thank you.
