The new WordPress version of 4.8 will strip out content and code in custom widgets. You will lose any content or code in this widgets upon an update and there is no way to retrieve it outside of site backup restore or manually re-entering. A new version will be out to fix this so just wait until you see that 4.8.1 is available. This applies to all WordPress installs not just Shape5 ones.
