The thing about the Flash on CW, they have to appeal equally to comic book readers and non-comic book readers (or casuals). There's even people who love the Flash who aren't into superhero shows at all. So they don't want to confuse people with explaining every little comic book thing in detail. There's a lot of complicated speed force logic that I doubt the show will ever explain unfortunately. It doesn't help that it's a CW show, which means more relationships and filler. That's why I enjoy Agents of Shield from ABC much better.
