It is normal as it is, if you need inside bleed, like with wire-O-bingings, then you will have to separate single pages to separate spreads but also create content with inside bleed.
Set the Inside Bleed to 0. Most common binding methods don’t require inside bleeds. The inside spine edge is folded not trimmed. If you provide a bleed it would get removed when the pages are imposed by the printer.
Is your doc set up as facing pages? It looks like you're bleeding on the inside of the page, which is what you need if the printer wants bleeds. Typically that's cut off, so you shouldn't need to worry.
