I need help :/

So I’ve been playing this world for a while and recently I’ve been having this issue where I link up with fence posts, glass panes, and walls. My character is linking up to these things, even when I have nothing in hand. I have 85.6mb worth of data in this world and I am playing mobile bedrock. (Don’t judge, it’s easier than dragging my ps4 over to my babysitting gig every time and he plays on his iPad) I have one free pack established in the world, the hikers guide or something like that. Cheats are off and it’s survival. I’ve been having this issue even before the pack was added to the world, and I’ve been able to log out and shut down the app to make it stop, but now that’s not working half of the time. This last video is the worst of it recently, I link up with all that stuff and I’m randomly put in swimming mode when I link, or on a padded dirt path. The random swimming mode is new. My phone is up to date and my app is up to date and I have at least 3 GB of free space on my phone still. What do I do now??
