I found a trail ruin, i dug out the gravel and it was only 1 block deep! I tried with another one, and it had the same issue.

We're tracking this issue at MCPE-169988, so I will resolve and link this ticket as a duplicate.
How far down did you dig? I thought I had this issue at a trail ruins in my world, so I made creative copy and used commands to remove all of the dirt and stone around the area. The large structures were located between 15 and 42 blocks below the top that stuck out of the ground.
If you have dug out 40 blocks down and still find nothing please respond with the seed and coordinates so that we can confirm.
