Hi there and welcome
If you want to restore it to the default, then please right click anywhere on your toolbar inside the toolbox.
Select Toolbox Toolbar
Click on Reset to Default
It will prompt you for a selection to reset to default Select Yes
This will then restore the toolbars to how they were when you first installed Corel
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Else let me know the results please.
