Hi,
There is a option to remove all handles in your style details window, to remove all handles on one specific unit, please select the unit > right click > change selection style > Handle Type : select No handles.
If its, that there is a unit showing a extra handle where it shouldn’t, please can you report this via the “Report a Remedial” feature located on your Home Tab, and we can investigate the issue further.
Thanks!
Ollie
