According to the code it tries to restore in a certain order:
/* Restore routes in correct order:
* 0. ones for local addresses,
* 1. ones for local networks,
* 2. others (remote networks/hosts).
*/

Works for me:
$ sudo ip route save > ro.save
$ sudo ip route flush all
$ ip ro
$ sudo ip ro restore < ro.save
$ ip ro
default via 192.168.1.1 dev wlp3s0 proto dhcp metric 600
169.254.0.0/16 dev wlp3s0 scope link metric 1000
192.168.1.0/24 dev wlp3s0 proto kernel scope link src 192.168.1.101 metric 600
Might be something related to your usage of Docker..... or maybe
the problem has just been fixed since you reported it.
For the record I'm testing with:
$ dpkg -l iproute2
Desired=Unknown/Install/Remove/Purge/Hold

$ uname -a
Linux nyera 4.14.0-2-amd64 #1 SMP Debian 4.14.7-1 (2017-12-22) x86_64 GNU/Linux
Would be great if you could test and see if you can still reproduce this
problem, and if so then please send us your save file so we can use that
for testing.
