OLED LoRa Sender (and receiver) sketch problem

Hi to all
I work with Heltec Wifi LoRa V2 and arduino web editor. Sketch OLED LoRa Sender (and receiver) can not be compiled. Returns error: line: Heltec.display->drawXbm(0,5,logo_width,logo_height,logo_bits);
‘logo_width’ was not declared in this scope.
Others samples sketches works fine.
Please help.

see if there is this file.
