TinyMCE customization error

Hello Guys, my name is Burkay. I’m having trouble customizing the TinyMCE in Devstack. Normally I didn’t have any problems in frontend-course-authoring TinyMCE editor, but when I installed the ‘frontend-lib-content-components’ app for customization, the data didn’t show up in the editor. I did not change the props, they are the same as the default ones. I don’t know what to do, can anyone help?

After updating to v.1.87.0 the problem was solved. I wanted to provide information for those who have similar problems.
