apt update && apt upgrade -> package can be upgraded

Using Ubuntu server 18.04. When I try with "apt update && apt upgrade", I get a warning:

1 package can be upgraded. Run 'apt list --upgradable' to see it.

If I then try with suggestion, I get:

Listing... Done
libneon27/bionic-updates 0.30.2-3~ubuntu18.04.1 i386 [upgradable from: 0.30.2-2build1]
N: There is 1 additional version. Please use the '-a' switch to see it

What is wrong (if something)?

UPDATE: "apt-cache policy libneon27":
