Blinking led when Mash enabled on Flashback 2 delay

I love the Flashback 2 delay, I bought it when it was updated with tap tempo. I also found the blinking led very useful, to always know in what tempo the pedal is. After a few months, I now want to experiment with the Mash and bought an external tap tempo. But when I enable the Mash, the led stops blinking! Why? TC, can you please do an update to have the blinking led in combination with Mash? That would be amazing.
