V7.1 - IP Route gateway becomes invalid when using pppoe interface with spaces in the name

Just switched my home 4011 from 6.49.2 to 7.1 and noticed an issue with some of my routes when it finished upgrading.

Version number: 7.1 (stable)
Router’s model: RB4011

Problem: If you have spaces in your interface name (eg: “PPPoE - ISP NAME [100/40M]”) when entered as a gateway the route will be invalid and loose its defined gateway.

Click OK

Route becomes invalid, looks like this:

After renaming the interface to something like “pppoe-ispname” there is no issue and the route is accepted.
