To assist in learning I suggest *not* using the zone file syntax *shortcuts*. 
This  will enable you to see what BIND sees.  Based on the zone information 
you have above, below is your zone file as BIND see's it(without the 
shortcuts).

mylan.lan. 86400 IN   SOA     bonsai.mylan.lan. root.localhost. (
    200718740
    28800
    14400
    3600000
    86400 )
mylan.lan.           86400   IN   NS      bonsai.mylan.lan.
1.mylan.lan.         86400   IN   A       127.0.0.1
2.mylan.lan.         86400   IN   A       192.168.100.1
Azalea.mylan.lan.    302400  IN   A       192.168.100.5
Azalea.mylan.lan.    302400  IN   TXT  "3109b3d6e9ef1a0f01e89f135933477030"
pine.mylan.lan.      302400  IN   A       192.168.100.49
pine.mylan.lan.      302400  IN   TXT  "31cc68c5aeef56368c390717062cd52286"

Is this what you are expecting?  Notice that "bonsai.mylan.lan." does not 
have an "A" record.  If a hostname doesn't have and "A" record then it cannot 
be resolved to its IP address.  Since it's name cannot be resolved, BIND is 
warning you about this in the log file.
This looks like what I am expecting. The "Azalea" and "pine" entries are inserted by ddns.  With what you "translated" for me, I am not clear how to insert the A record for bonsai.mylan.lan
