Adding posts updates previous post

Intermittently adding a new post will cause the previous post to be updated with the new posts information, instead of it being inserted.

In the _posts table it looks like a normal revision of an old post but it was definitely added via the add new post page.

Wordpress version 5.2.1
Adding the post manually through wp-admin. Not using code. Only happens with and “editor” user, can’t make it happen with admin. Tried deleting user and making a new one but same problem.

Below is the _posts table after “adding” 6 posts, as you can see test post_4 is updated by test post_5. So there only ends up with 5 posts instead of 6.

id post_date post_title post_status post_name post_parent post_type
1145 2019-06-14 13:22:44 test post_6 publish test-post_6 0 post
1146 2019-06-14 13:22:44 test post_6 inherit 1145-revision-v1 1145 revision
1144 2019-06-14 13:22:31 test post_5 inherit 1142-revision-v1 1142 revision
1142 2019-06-14 13:22:19 test post_5 publish test-post_4 0 post
1143 2019-06-14 13:22:19 test post_4 inherit 1142-revision-v1 1142 revision
1140 2019-06-14 13:22:08 test post_3 publish test-post_3 0 post
1141 2019-06-14 13:22:08 test post_3 inherit 1140-revision-v1 1140 revision
1138 2019-06-14 13:21:58 test post_2 publish test-post_2 0 post
1139 2019-06-14 13:21:58 test post_2 inherit 1138-revision-v1 1138 revision
1136 2019-06-14 13:21:44 test post_1 publish test-post_1 0 post
1137 2019-06-14 13:21:44 test post_1 inherit 1136-revision-v1 1136 revision

Any ideas what the cause of this could be?
