In Catalog Manager and on the Insert Symbol By Name dialog, the preview of the selected symbol appears "zoomed out" so that the symbol is very small. Opening and re-saving the symbol in Create Symbol does not help, nor does rebuilding the catalog.
There may be elements present in the symbol drawing that are a significant distance from the visible symbol graphics. These elements are affecting the calculation of the extents of the symbol graphics and may or may not be visible themselves. In past cases they have been found to be empty Text or Text Node elements and therefore not visible, but there could be other element types.
This same problem may affect previews for other items such as title blocks or project pages. Adapt the steps below for those items. For example backup the title block using Export Catalog, open the title block using Title Block Designer, proceed from step 3 in the steps below.
