clearCompiledTemplate and clearCache doesn't work in v5

[criocere]

I switched on Smarty V5 after months but I discover that clearCompiledTemplate and clearCache when specifying some specific cache to remove doesn't work anymore

clearCompiledTemplate() and clearCache() are ok (no parameter)

clearCache
clearCache(null, 'Desktop|myTemplate') for exemple is ko (if I use smarty v4 lib, it works!!!)
note 1: my structure is "Desktop|myTemplate|id of my page"
note 2: I executed clearCache(null, 'Desktop|myTemplate') and I checked my cache and the folder "Desktop|myTemplate" is not deleted/emptied

clearCompiledTemplate
clearCompiledTemplate('myTemplate.tpl') is ko on my side (but more difficult to see in the cache)

Doesn't something change on those function?

I spend almost one day, and I am blocked. I have to remove all, all the time even if I change only one templace :o(

Does someone have an idea of what change?
Thanks

Found after hours!!!
In cache creation mode I use "setUseSubDirs to true" and not when trying to empty the cache
