Hello
new to this so any helpful advice is appreciated .
watching a movie ( PC windows7 / KODI v17 ) – addon is Crackler , subtitles from opensubtitles.org enabled / as movie runs the desired subtitles occasionally change for a short period into a mixture of action buttons ( like stop , go back , fast forward ……) with a background of subtitles in a different color and size – 
?
Thanks
Michael
