Beams auto deformed when placed in certain areas

[Anonymous]

hey, so I just want to make a good old standard beams, but when placed in this area, the beams seems to be deformed like the picture which i have attached in this post (highlighted in blue), it didnt look like that if the beam was placed anywhere else, any idea why?

You may have to change the join order with whatever is intersecting the beam causing the weird cut-out shapes in the beam
