Xray bug in realms

I have my own Minecraft realm and I went into the nether to get some quartz ore for buildings and observers. after I came out the nether it didn't bring me back to the nether portal I Made and it had this weird xray glitch and I hate it can you please fix this and it didn't happen on a different device. I know this photo isn't clear but after this my Switch Crashed and I don't want to try again.
