Ckeditor ruby gem adds ">" at the end of the entries every time a user edits the textarea entry - ruby-on-rails

Question

Ckeditor ruby gem is adding a ">" at the end of my content entries every time a user edits the content.
Here is a video of it happening: https://drive.google.com/file/d/16sus8LGxHBZLFs_ts5_SJJSwLfisJzom/view?usp=sharing
Here is my update_row controller code for the text_component model. The textarea input is being saved in the content column.
def update_row
#text_component = TextComponent.find(params.fetch("id_to_modify"))
#text_component.tab_id = params.fetch("tab_id")
#text_component.content = params.fetch("content")
if #text_component.valid?
#text_component.save
redirect_to("/guides/"+params.fetch("guide_id"), :notice => "Text component updated successfully.")
else
#guide = Guide.find(params.fetch("guide_id"))
render("guide_templates/show.html.erb")
end
end
ANSWERED: here is the working form code in my edit_form view:
<form action="/update_text_component/<%= #text_component.id %>" method="post">
<!--input for guide_id -->
<div class="form-group">
<input type="hidden" id="guide_id" name="guide_id" class="form-control" value="<%= params.fetch("guide_id") %>">
</div>
<!-- input for tab_id -->
<div class="form-group">
<input type="hidden" id="tab_id" name="tab_id" class="form-control" value="<%= params.fetch("tab_id") %>">
</div>
<div class="form-group">
<label for="content">
Content
</label>
<textarea id="content" name="content" class="ckeditor" rows="10"><%= raw #text_component.content %></textarea>
</div>
<button class="btn btn-block btn-outline-secondary">
Update text component
</button>
</form>
