That seems to be in the 'budget' category for store-bought stuff, which is not intended as a criticism by the way. After doing some lab tests on various composts, I've found you kind of get what you pay for.

You've already found it has some sand, and if your soil is heavy (clay) that's not a bad thing. It does take up space in the bag that would otherwise be organic matter, which is another way of saying the bag isn't all compost. That's one reason it's cheaper than the 'premium' compost products.

The bag of Lowes cow manure I analyzed last year (which is probably not from the same original source, but just to illustrate) was relatively low in organic matter, middle of the road on nutrients and total salts (conductivity), and pH was neutral.

There is certainly nothing wrong with this stuff and I've used many bags of inexpensive compost and topsoil from the big box stores.
