Converted my catalogue from PSE10 to PSE15 recently. Now I don't see any version set arrows to open and close sets. I see the stack symbol but only the top pic of the version set. Can't open the stack. All pics in set are there, but can't see them. Also any new pics added to PSE15 catalogue that are edited and saved in version set can not be opened nor do I see the arrow to open. Stack symbol shows on those too.
