Cannot remove know-how protection from some DBs

[armandodm]

Hello guys!

I am facing a problem removing the know-how protection from some DBs, I'll give you the entire context:
I want to see the cross-references of some variables inside some DBs, but I cannot remove the know-how protection from these ones, this program is from a Sidel Series 2 rotary blower machine, the PLC is an S7 414-2, the backup was made with simatic manager, the hardware includes some FM 352 cam modules, so when I tried to migrate the program to TIA Portal V13 it couldn't migrate some DBs (the ones I am having problem with) because I was missing UDT1, I looked for info about it and I found that UDT1 was part of the cam modules, so I look for that UDT1 in the example projects from the config package of the FM 352, then I could finally migrate all the DBs, but these DBs from the cam modules have know-how protection, and I cannot remove it, when I right-click the DBs to see all the options the know-how protection option is not even there... so I would like to know why this is happening and find a solution
I'd really appreciate your responses, thanks for reading
