Hi everyone,
WBS Gantt in our Jira project suddenly ceased to work properly.
Whenever we try to set an issues „manual” option to „yes”, after refreshing the gantt chart it resets to the default „no”.
I did the following:
(1) Set „manual” to „Yes” modify the „start date”, and save.

(2) After saving, everithing looks fine.

(3) Clicked refresh, and everithing jumped back to default, and corrected the start date according to the dependency, which it should not because of the „manual” setting.

I tried to modify the settings from the jira end in „table” view:

(1) Clicked in the issue.

(2) Clicked in the „Open WBS Gantt Chart” option and modified the „start date” and the „Manual mode” to „On”

(3) Upon closing and reopening the issue, all the modifications were lost.

Lastly, the settings of the addon, and the issue window showed a couple of errors:

Modified the settings, to „(Create new custom field)” and clicked update, so the page looked like this:

After refreshing the page, every modifications become lost:

Has this happened before to anyone? Why is this happening?
