Ola Hallengren Index Optimise Script not Rebuilding Indexes
Your index only has 679 pages. Ola's solution is set to ignore indexes with less than 1000 pages (see the @PageCountLevel parameter). You can override that so that it cares about indexes with fewer than 1000 pages, but why? Wasted effort IMHO.

I would stop worrying about small tables like this - let Ola's solution do its job, and worry about fragmentation when you can actually prove it is causing a tangible performance problem for a specific index. "Fragmentation is high" is not a problem on its own.
