unwanted text appearing in widget sidebar

i am using flexmarket theme.
i have added several widgets to the sidebar of my site.
for some reason there is text appearing at the bottom of the sidebar on how to place a widget as follows

“sidebar widget
go to appearance > widget to add sidebar widget into this area.”

i deleted all the widgets to see if the text would disappear but it duplicated itself, ie, there were to instances of the same text appearing.

this is a typical page link
https://www.vintagebrickroad.com/store/products/cow/

it shows at the bottom right of the page the unwanted text.
this appears on every item page.
anyone else having this problem or solution
thanks
