Location of chemicals in Eco Online

There is a confusing listing over the locations in the newest version of Eco Online. In the old version there were plus signs indicating that there were more sub-locations under the "main location", while in the new version there are arrows instead. This causes people to misunderstand to click on the actual text of the location and find that there are no chemicals registered there. There is also an indication behind the text of the number of chemicals registered at the main location. In our case, we did not register chemicals directly into the main location but in the sub-locations.
our suggestion is better visualization of the locations so that users of the program do not misunderstand the number of chemicals or where to find them.
