When I try to add an issue through the Gantt-chart (plugin by @FrankPolscheit), as soon as I click the "Checkmark" (Accept) button in the form inside the chart, the whole form turns red and an error message is displayed:
Error creating issue:
Field 'Planned Start (customfield_10010)' cannot be set. It is not on the appropriate screen, or unknown.
Field 'Planned End (customfield_10011)' cannot be set. It is not on the appropriate screen, or unknown.
It feels like I probably screwed something with the configuration, as I've just installed the plugin for evaluation.
Did anyone have similar issues?
