A configuration can exist with the free-days value never entered. Dockflow treats an empty value the
same as no rule. Open Dwell Center and check the combination in question actually carries a number.
Example
A configuration for a combination exists, but the free-days field was left blank. Dockflow treats that empty value as no rule, so the expected free days do not apply. Open Dwell Center and check whether the combination in question actually carries a number; if it does not, the rule is genuinely not filled in.
