Block won't be solid

Hello, im new to Mcreator and have basically no knowledge about coding. Im trying to make a furniture mod and I created a chair and a table. I made it that when you leave the seat the seat will test if the blocks around it are solid and teleport you to the next free block. When I created a table I changed the transparency type to solid, but the seat won't recognize it and teleport me anyway right into it if its right in front of the chair.
