Remove dotted lines from previous text placement

[LaurenDelRey]

Hi there! having trouble finding the answer as to how to remove the dotted lines from a previous text placement after i move said text.  It remains visable no matter what i've tried. And when i try to add filters to the current text, such as emboss, it only applies the filter to the ghost dotted text.  Any help would be much appreciated.  (brand new to Gimp)

Thank you!
