LX60 Aleos Softw 4.15.3 and Radio FW WP6707_02.37.03.00 GENERIC couldn't find to set/change APN

After updated the LX60 to Aleos Software Version 4.15.3 Aleos Build number 003 and Radio Module Type WP7607 Radio Module Identifier Generic , Radio Firmware Version SWI907Y_02.37.03.00 73df45 jenkins 2020/04/08. It isn’t possible to change the APN. In the TAB “WAN/Cellular” General i couldn’t find to change the APN ? If we look to the manual https://source.sierrawireless.com/resources/airlink/software_reference_docs/airlink-lx-series—configuration-guide/ It seems we don’t have the posibilty under the tab Cellular General => Network Credentials : No APN in use visible or overwrite APN is on the screen ?

Configuration found under the TAB SIM Slot 1 Configuration. Thx
