REFIND do not propose to launch ubuntu

[geole0]

Hello

A USB key to install ubuntu 19.04 has been created.
The first decision is to install REFIND in the ESP boot partition.
As the computer is not very standard with the EFI, REFIND had to be duplicated in the EFI/BOOT structure then in the EFI/Microsoft/Boot structure
Then UBUNTU was successfully installed with the ubiquity -b command

Here is the description of the partitions containing the UBUNTU done by boot-info

=================== sda2: Location of files loaded by Grub: ====================

   4.297847748 = 4.614778880 boot/vmlinuz-5.0.0-13-generic 2
   4.297847748 = 4.614778880 vmlinuz 2
   4.757804871 = 5.108654080 boot/initrd.img-5.0.0-13-generic 3
   4.757804871 = 5.108654080 initrd.img 3
   4.757804871 = 5.108654080 initrd.img.old 3

During the reboot, refind proposes icons for the boot files contained in the partition SDA1 but forgets to propose VMLINUZ-5.0.0-13
It seems to me abnormal.
