This is a phenomenon that occurs because unnecessary tags are included in the process of copying and pasting content from other files (Hangul, etc.) when entering content in the description or outline of resource/activity in the classroom.

1. Modify the description or outline of the resource/activity immediately preceding the abnormal arrangement phenomenon.
2. Copy the text content in the description or outline of the resource/activity → paste it into the notepad to remove the tag, then copy and paste the content of the notepad again. Or, if you want to paste without unnecessary tags, paste with ctrl + shift + V instead of ctrl + V.

If it is not resolved by the above method, please contact the administrator of the university/institution.
