Recently we upgraded tfrom 3.0.0 version to 14.7.0 for the support of control contents.
Thanks for your inquiry. I would suggest you please upgrade to the latest version (v14.10.0) from here and let us know how it goes on your side.
If the problem still remains, please create a standalone/runnable simple Java application that demonstrates the code you used to reproduce the shared issue and share it here for testing purposes. We will then provide you more information on this along with code.
