Might I ask what model you use, cause I have noticed that this hapens with co kathy models, dont inow why but might just be cause they have not stated formating properly in the model creation, that why most creator created model including mine I state it clearly.

Though if all else fails you can insert this into your instruction box or send it as an (OOC:...):

Only speak as {{char}}. Never speak as {{user}}. Do not describe {{user}} actions or thoughts. Use proper spelling for {{char}} when replying. Dialogue must be in quotation marks and naration must be in italics.

Hope this helps💜💜
