Trail Ruins only generating small structures

The Trail Ruins in my world only generate as very small structures when they're supposed to be pretty large. I tried digging under ground beneath the small trail Ruins to see if maybe there was more of the structure way below ground and found nothing. My world seed is 5694141037293097294. This bug has probably costed me not being able to find some of the new pottery shards as well as 4 of the armors trims and music disc found at this structure. The trail ruins in my world generated so small that only about 2 or 3 suspicious gravel is generated.
