The problem is they fit TOO well. We struggle to get either relativity or QM to deviate significantly close to their “realms”. However, neither predicts the existence of the other, and are incompatible in basic ideas about reality.
Basically, we know they don’t align, but we can’t access the middle area, and we can’t find any useful cracks to pry at within the accessible areas. It’s been driving physicists up the wall for decades.
