RD-8, sometimes when pattern play is stopped, it never plays again without power off/power on unit

New

My RD-8, sometimes when pattern play is stopped, it never plays again without power off/power on of the unit.  I will even go to 'steps', and it shows no steps lit for different drum sounds.  They come back after reboot.


Anyone else come across this issue?  I have the 'latest' update that I am aware is available as of 2021-03-17.  Thanks.
