Faulty Component pasted and cannot get deleted

Good morning,

while copy & paste from one to another workflow to tidy things up, I encountered a problem which I struggle to resolve.

A component was inserted which I cannot properly select and therefore delete. All nodes were inserted without any connection. Presumably because I selected some nodes via bulk- and others single selct by pressing CMD + Shift.

I can change the description of the faulty component and connect the input ports. Upon configuring the component it has no included “sub-nodes”. Not even in- and output which I believe is the primary issue. The context menu also does not offer the usual component configuration menu. Lots of errors are thrown as well and I cannot save the workflow.

Adding to this I also cannot replace the component by another copy nor any other node. Configuring the node I am able to paste all containing nodes but, unfortunately, not the in- and output nodes of the component.

Since I cannot save the workflow and I want to preserve the status quo for debugging, I neither can share it nor will I close knime in case this becomes so important to remotely debug.

Best
Mike
