Unable to get value of vote (average or user) from entity that has been voted on with fivestar

I've tried this both with votes directly on an entity (tried with node and user) and with votes on a separate target entity (again nodes and user).

If I try to use the data selector to access the value on a fivestar field, it gets as far as vote:user:field-rating: or similar but doesn't offer any further options after that last colon.
If I try to set the value, however, ('set a data value' action) it will show vote:user:field-rating:average-rating (or user-rating).

I also get a bunch of notices when trying to congifure these rules, not sure if they're relevant:
Notice: Undefined index: label in rules_rules_core_data_info_alter() (line 137 of .../sites/all/modules/rules/modules/rules_core.rules.inc).
Notice: Undefined index: label in RulesPluginUI::getOptions() (line 861 of .../sites/all/modules/rules/ui/ui.core.inc).

Additionally, I see this notice when installing the module.
Notice: Undefined index: label in rules_rules_core_data_info_alter() (line 137 of .../sites/all/modules/rules/modules/rules_core.rules.inc).

And finally, I see this on the status report:

The following tokens or token types are missing required name and description information:

$info['tokens']['vote_results']['count-vote-cache-id']
$info['tokens']['vote_results']['count-function']
$info['tokens']['vote_results']['average-vote-cache-id']
$info['tokens']['vote_results']['average-function']
$info['tokens']['vote_results']['sum-vote-cache-id']
$info['tokens']['vote_results']['sum-function']

This last bit in particular seems like it might be relevant.
