Spread Algorithm is not working after upgrade to 1.5

We had set the spread algorithm to be the default algorithm within the nomad server configuration. This was working up till we upgraded from 1.3.6 to 1.5.3. When I query the server for its scheduling config I get the expected response


When I then check an allocations placement metrics I can see binpack is still being used

| Node                                 | binpack | job-anti-affinity | node-reschedule-penalty | final score |
| 82273c80-f2f7-3aa9-f4ae-def7966d619b | 0.442   | 0                 | 0                       | 0.422       |

Am I missing something because I don’t see anything in the release logs other than a bug fix in regards scheduling -inf.
