Hi,
I am use to remnote, im just wondering if anyone know why some line should appear on colon.
it seem as those one are not appearing in my flash card or i could be wrong. It is coming up where Myoplasticity but not in hyperplasia
The line through the double colon indicates that the card that is generated by the rem is disabled/deactivated (will not appear in your queue). You can use keyboard shortcuts to enable/disable a card (? in the bottom right > Keyboard Shortcuts), or the Cards icon 
in the bottom toolbar.
Ohhhhh thank you!!
It was annoying me so much!
