Undeclared EXTI_0_IRQn & EXTI15_4_IRQn

Hello to all,
I'm coding a simple project for STM32WL55IC7 MCU, for the NUCLEO-WL55JC2 board. I didn't use the BSP for the board, in other words i didn't select the NUCLEO board option, but I started the project using the MCU.
The Project name is STM32WL55IC7_foo. The CubeIDE build the following 3 projects:
1. STM32WL55IC7_foo
2. STM32WL55IC7_foo_CM0PLUS (the code for Cortex M0+ code)
3. STM32WL55IC7_foo_CM4 (the code for Cortex M4 code)
When I try to compile the project, while the CM4 core code is compiled without any error, the code for the M0PLUS core issued errors, on the following snippet during the EXTI interrupt initialization:
/* EXTI interrupt init*/
HAL_NVIC_SetPriority(EXTI1_0_IRQn, 1, 0);
HAL_NVIC_EnableIRQ(EXTI1_0_IRQn);
HAL_NVIC_SetPriority(EXTI15_4_IRQn, 1, 0);
HAL_NVIC_EnableIRQ(EXTI15_4_IRQn);
The issued error messages are:
Description Resource Path Location Type
'EXTI1_0_IRQn' undeclared (first use in this function); did you mean 'EXTI15_10_IRQn'? main.c /STM32WL55IC7_foo_CM0PLUS/Core/Src line 142 C/C++ Problem

'EXTI15_4_IRQn' undeclared (first use in this function); did you mean 'EXTI15_10_IRQn'? main.c /STM32WL55IC7_foo_CM0PLUS/Core/Src line 145 C/C++ Problem
But the interrupts numbers are already defined on the file stm32wl55xx.h (by the CubeIDE):
/************* STM32WLxx specific Interrupt Numbers on M0 core ************************************************/
EXTI1_0_IRQn = 4, /*!< EXTI Line 1:0 Interrupt */
EXTI3_2_IRQn = 5, /*!< EXTI Line 3:2 Interrupt */
EXTI15_4_IRQn = 6, /*!< EXTI Line 15:4 interrupt */This file is on project path STM32WL55IC7_foo/Drivers/CMSIS/Device/STM32WLxx/Include/stm32wl55.h
It should be valuable if someone have any idea about this issue
Thanks
