Issue Deleting Multiple Queue Items – "Can't read property of undefined"

I’m facing an issue with deleting multiple items from a queue in OpenFlow.

When I try to delete multiple queue items at once, the operation fails and shows the following error:

“Can’t read property of undefined”

However, when I delete the items one by one, they are removed successfully without any errors.

sometimes it bugs out, make sure to “Clear Selection” before doing again the full selection

In the web interface you have a “purge” option on each queue, to delete all items.
If you want to delete multiple items, it is usually also easier to do using the webui ( thou as @Anono_Nono mention, that also sometimes need’s two tries )
