Workbench GUI don't show the custom cost

Hi, I have a problem ... well I don't know if it is.
Since I do not know if it is something that is not enabled through the plugin.
When I put in the new costs to unlock some items, the new costs do not appear in the WorkBench GUI.

From already thank you very much.

As stated in the documentation, the Tech Tree UI cannot be changed. The best we can do is show a popup when a user tries to unlock something, which has not been implemented.

Ok thanks
