MS Intune not synchronize warranty dates in the assets

Dear Community,

I am trying to synchronize Intune with Freshservice. Sync went well and all assets are visible but I can not get the warranty dates sync into the asset. 

To make it happen we have to match during Intune assets import, the field "manufacturer". But it stays empty during sync. If Manufacturer is empty, the DELL module cannot do the match and then capture warranty date.

I am using Intune App on the market place
 

Any advice?

Thanks,

Sara
