Problems with new Refresh Button

Hi team…I’m facing with an error in Table view and multiple selection widget whenever I press the refresh bottom I see some strange characters in table view and widget as shown below:

before clicking refresh button:

afterwards:

attached a sample of my wf:

Insert GAp Information _ Sample Forum.knwf

I didn’t test in KNIME server yet, this error occurs in AP.

Just an additional question, is there a way to customize refresh button stile via css?

tks in advance.
