The constraint #channels <= 1 means that your software AP must operate on the same channel as your Wi-Fi client connection see the channel setting in nf below.

Total <= 2048, #channels <= 1, STA/AP BI must match The capability is listed in the following section in the output of iw list: Using that capability you can create a software AP acting as a 'wireless repeater' for an existing network, using a single wireless device. Many wireless devices even support simultaneous operation both as AP and as wireless 'client' at the same time.
