I am not using docker, i used this fix

[https://review.discourse.org/t/fix-ignore-removed-delete-when-reminder-sent-bookmarks-column/13647](https://review.discourse.org/t/fix-ignore-removed-delete-when-reminder-sent-bookmarks-column/13647)

then

rake assets:precompile

doesn’t work, maybe another alternative that i don’t know?

rebuilding did not resolve this issue for me also on 2.5.0 / stable branch with docker

At this point I recommend you move to the beta branch.
