We have a screen for file upload which has button with label "Select files". It should be displayed as "Select file(s)" and there is OOTB field value for that. However in version 8.7.1 it displays "Select file #40;,,," instead (please check a screenshot).
Without parenthesis it displays normally, though. Not sure if there are some known issues with field values in Pega 8.7.1?
