This can have a number of reasons:
- The set containing the abbreviation may be disabled. Make sure that its checkbox is turned on in Typinator's set list. When this checkbox is turned off, the items are still available in Typinator's Quick Search, but Typinator will no longer consider items in this set as you type.
- Items in the set may conflict with items in other sets. Take a look at the list of abbreviations and look for warning symbols in the first column. When you select an item with a warning symbol, Typinator displays an explanation beneath the abbreviation field.
- The set may be disabled for one or more (or even all) applications. To assign sets to applications, click the button with the application symbol at the bottom right of the set list. For more information, see the section "Activating sets for specific applications" in Typinator's User's Guide.
