Why does the lamp not work correctly when switching modes?

Hello！ In the lighting circuit there is: an incoming line, a through switch and a garland of five three-mode （illumination, general light and all together） led lamp. Modes are switched by switching the switch key. The problem is that each time the mode is switched, the last lamp （when turned off） changes pulse mode and the next time it is turned on, it lights up with the others in a different state. No flickering, lights with a transform unit. The malfunction is excluded, the connection of resistance to it, as in the case of blinking, was not tried. How to solve the problem？ Thank you！
