Yep, your right monitor may not be fitting well, but I'd also check to see if it's not simply insertion-related first, as it seems to be the case IMO, when looking at the picture. Sometimes it may take a bit of practice to fit silicone CIEM's due to their initial friction against ear walls. Please try twisting the monitor in when inserting and that should help locking it properly in place. The upper part of the monitor should definitely be underneath your pinna, as @davidcotton mentioned already.
