Cisco MDS : Setting boot variables fails with 'mismatch between actual image type and boot variable (0x4045001E)'

Syntax to use to set boot variables as follows:
switch(config)#
no boot system
switch(config)#
boot bootflash:<kickstart new_kickstart_image_name>
switch(config)#
boot bootflash:<system new_system_image_name>
switch(config)#
end
switch#
copy running-config startup-config
switch#
reload

Customer running the following command on a MDS 9148S:
MDS9148S(config)# boot kickstart bootflash:m9148-s6ek9-kickstart-mz.9.4.2a.bin

Performing image verification and compatibility check, please wait....
Failed to configure bootvar kickstart for sup-1: mismatch between actual image type and boot variable (0x4045001E)

Incorrect image being used for Cisco MDS9148s platform:
From MDS9148s:
MDS9148s# show version
  kickstart image file is: bootflash:///m9100-s5ek9-kickstart-mz.6.2.23.bin
  kickstart compile time:  3/31/2018 23:00:00 [02/20/2018 18:47:57]
  system image file is:    bootflash:///m9100-s5ek9-mz.6.2.23.bin
  system compile time:     3/31/2018 23:00:00 [02/20/2018 19:58:46]

Note that show version from switch is :
-m9100-s5ek9
But trying to set boot variables with image from a different platform, which will fail :
-m9148-s6ek9

Ensure correct system/kickstart images are used for each platform 
Platform images can be download from for each switch type :
