SKR PRO, TFT35, USB and SD question

Greetings from Miraflores, a town in Madrid, Spain. This is my first message in the forum and first of all I want to congratulate Ryan and the rest of the team for his great work. Second apologize if I do not understand very well, I barely speak English and I have to use an electronic translator, this is also the cause that may not understand anything about the assembly.
I wanted to ask for your help about the Lowrider CNC 3 that I have started to mount. The problem is that I have tried the board (SKR Pro V1.2 with marlin_v1cnc_skrpro_duallr_2209_2.1.1_515) and the screen (TFT35 E3 V3.0.1 with Bigree_TFT35_V3.0_E3.27.x) and observe that with the screen in Touche SCREEN mode I can access:
• USB memory in TFT35
• The SD card on TFT35
• The SD card on SKR Pro And
And with the screen in Marlin mode I can only access the SD card on SKR Pro. Is this normal? or should be able to access the USB and SD in the TFT35 in Marlin mode.
Thanks.

That is normal now. Marlin mode has moved the sdcard to the skr pro, to enable the wifi interface.

Muchas gracias
