You are not alone, I found reports of gardeners in your growing zone with reports of similar activity among the fruit trees.
The low number of chill days this past winter and the record setting drought are the environmental issues that most reports are listing as to why the trees are showing 2nd blooms and crops.
Fruit may be small and even inedible.
Pick the fruit as it ripens even if it is not edible. Don't leave fruit on the tree.
