Why does my file have multiple crtime entries?

Using ext4 filesystem I was able to read out the creation time of a file using the approach here . As a result I am indeed provided with a table featuring the crtime (creation time) of the inode(respective file) in question. What confuses me and to which I could not find an answer in the man debugfs is why it shows me 2 lines with crtime, moreover not even being the same time. This is the output I get [user ~] $ sudo debugfs -R "stat " /dev/sda2 debugfs 1.43.1 (08-Jun-2016) Inode: 274742 Type: regular Mode: 0644 Flags: 0x80000 Generation: 3666549610 Version: 0x00000000:00000001 User: 1000 Group: 1000 Project: 0 Size: 0 File ACL: 0 Directory ACL: 0 Links: 0 Blockcount: 0 Fragment: Address: 0 Number: 0 Size: 0 ctime: 0x57b4c632:1e30ee34 -- Wed Aug 17 22:16:50 2016 atime: 0x57b4c4c0:afa082b0 -- Wed Aug 17 22:10:40 2016 mtime: 0x57b4c632:1e30ee34 -- Wed Aug 17 22:16:50 2016 crtime: 0x57b4c4c0:afa082b0 -- Wed Aug 17 22:10:40 2016 crtime: 0x57b4c632:(1e30ee34) -- Wed Aug 17 22:16:50 2016 Size of extra inode fields: 32 Also note that the second (and not realy correct) crtime is in brackets and equals the mtime, since I saved to the file obviously twice.
