Hardware Setup with >4 Led Outputs does not work

I am using release 0.14.0-b5, on a ESP32-S3 Devkit. Everything works just fine with one exception.
I have 5 Ws281x led strips. Each strip has 75 leds on it.
Strips 1-4 work just fine, but the 5’th does not even light up.
Yet, if I go into Config → LED Preferences and under Hardware setup I swap the GPIO pins of the 4 & 5’th strings, then the 5’th string works and the 4’th does not.

LED outputs are configured as such.
Segment 0 = Start LED 0, Stop LED 375

Then Under Config → LED Preferences
#1) Start 0, Length 75, GPIO 14
#2) Start 75, Length 75, GPIO 13
#3) Start 150, Length 75, GPIO 12
#4) Start 225, Length 75, GPIO 11
#5) Start 300, Length 75, GPIO 10

Any ideas what might be going on here?

What date is your 0.14.0-b5 (check Info → Build)?
Have you tried going back to 0.14.0-b4 or earlier?

Just to eliminate any bugs that may have crept into the the latest beta.

That setup should be fine.

Build 2309100
I have tried 0.14.0-b4 and a few before that, same thing.
With some searching the S3 only supports 4 RMT outputs.

Yes

Aha- missed the reference to S3.
That makes sense (unfortunately).
