Use Fixup>Run Fixup to display the Fixup options:

The actions in this list correct common minor errors in proofread documents. Most of the actions are self-explanatory and uncontroversial. You might consider disabling the first action, thus permitting Fixup to modify the contents of block markups. If you do, consider also disabling "Convert multiple spaces to single spaces" which can spoil the formatting of manually-formatted tables.

Click Go to apply the enabled actions throughout the document.
