What issue do you have?

If I append a space to the end of a line and wait a couple of seconds, the editor backspaces over it (deletes it). This results in many run-on sentences while typing.

Is this a bug or normal behavior?

Thanks.

What is it "Carat" ? No such plugin...
Anyway, By my side, in the RTE or the MDE nothing similar to your issue... Spaces at the end of line are not automatically deleted....
Joplin 3.4.1, Linux

It's not a plugin. The carat is the insertion point, the vertical flashing line, the cursor...

OK. I learn something...
