"Cut/Connectors/Place on Cut" not working

In Bambu Studio 1.7.7.89., I use the “Place on Cut” feature for connecters under the Cut tab. It worked one time and placed 4 dowels exactly where I wanted them. Everything worked out great. After that 1 time, the software refuses to put the connecters on the main piece. Ive tried it over and over but nothng seems to work. It will place the connecters on the plate but not on the piece you want it on. Has anyone used the feature and gotten it to be consistent?
