P radical cation implicit H atoms error

MarvinSketch 15.4.27. If I draw PPh3 (P with single bonds to three Ph groups), then place a +1 charge on P, then convert P to a monovalent radical, MarvinSketch incorrectly adds two implicit H atoms to P. However, if I then follow up with any other action, such as moving an atom's position slightly, MarvinSketch removes the two implicit H atoms. ??

Thank you for the report, this is a bug,the Ph oscillates between the 0 and 2 implicit H.

I've created a ticket and get back to you when this is fixed.
