Suddenly missing control of the IC's

Hi,

I have the following setup:

GLEDOPTO ESP32 WLED Controller With 4 Data Outputs. A WS2805 strip hangs on each output (1x with 33 ic’s, 1x 37 ic’s and 2x 18 ic’s)

This setup also worked without any problems. However, I have extended the strip with 37 ic’s (it was previously 32 ic’s) and from this point on a strip that no longer works properly with the 18ic’s. This now shows a maximum of 12 ic’s. The rest remains dark. At first I thought something with the strip was defective. But if I activate reverse , it works. But again only 12 ic’s. It doesn’t matter what I write in with LEDs, a maximum of 12 ic’s lights up. Resetting doesn’t help either. I’m at the end of my Latin, would be happy about any help

what is sent to the LEDs is defined in segment setup.
