Text box mix characters

[Xavi Martin]

When I change the value of the libreoffice interface (for example Paragraph Style, in left upper corner) the old value remains in the text box with the new value.
It's not easy to explain, please see the images attached in order, the action done is change the value of Paragraph Style from "Text Body" to "Default Text".
