Rewrite tag problem

Hi, in product page i have tags,
every time I create a tag and make a mistake or want to change or modify it, I'm unable to do so. For example, if I write "space" in lowercase and want to change it to "SPACE" in uppercase, I can't. How can I fix this? It always keeps the first saved version. Thanks.

Super! many thanks
