Software makers usually fix these issues but it can take them some time. What you can do in the meantime is to download and install an older version of OmniOutliner 5.7.

What's new in this version:

- Personal Subscriptions: OmniOutliner now has support for (optional) subscriptions! Subscriptions give you the latest version of the app, enabling every feature on every platform (including Pro features)—with a lower cost up front and predictable spending in the future. (If you prefer the traditional licensing model, that option also remains available: traditional licenses are investments which cost more up front, but save money in the long run.)
- Unified Trials: we’re unifying our trials to use a single, simple approach: you sign up for a trial, it lasts for two weeks, and then it ends without charging you.
- Omni Automation [PRO]: support for automation via JavaScript Plug-ins has been updated; detailed notes about automation enhancements and changes can be found in the API Reference Release Notes.
- Named Styles [PRO]: when duplicating a Named Style, the duplicate will appear directly under the original.
