RZ/T2M: clear timer1 when timer0 overflows

Question

Hello! 
 I'm trying to automatically clear a timer (timer 1) when another timer (timer0) overflows. 
 As stacks, among others, I've g_timer0 set to channel 0, g_timer1 set to channel 1 end g_elc. 
 In g_timer1's properties, I enable in Input, Clear Source, the checkbox "GPT0_OVF (GPT0 GTCNT overflow (GTpr COMPARE MATCH))". If I do this, I get the following error: 
 Description Resource Path Location Type g_timer1 Timer Driver on r_gpt: Requires an ELC peripheral function for GPT configuration.xml /test_irq Unknown Configuration Error 
 I did different trials in the event links tab too, but with no luck. The actual configuration is the following: 
 
 What Am I doing wrong? Thanks! 
 
 EDIT: 
 I solved by removing the checkbox in that option and using the following code to let g_timer1 use as source input the LLPP GPT Event A:

g_timer1 . p_api -> open ( g_timer1 . p_ctrl , g_timer1 . p_cfg ) ; 
 
 gpt_instance_ctrl_t * p_instance_ctrl = ( gpt_instance_ctrl_t * ) g_timer1 . p_ctrl ; 
 p_instance_ctrl -> p_reg -> GTCSR_b . CSELCA = 1 ; 
 
 g_timer1 . p_api -> start ( g_timer1 . p_ctrl ) ;

But I'd like to know why doing it via the FSP configuration doesn't work, thank you!

As per the RZ/T2 Flexible Software Package Documentation: General PWM Timer (r_gpt) of FSP v1.3.0 
 " The configurable ELC GPT sources are shared by all GPT channels. The event links for the ELC must be configured outside this module. " 
 Please check the Usage Notes of "Timer Driver on r_gpt"
