Yes, this is actually very common because contacts saved years ago usually come in vCard 2.1 format, while the latest phones, Gmail, and applications come in 3.0 or 4.0 format. When all these files are combined, most free merge tools get confused because they are designed to work with only one format. This often causes missing phone numbers, broken names, or even tool crashes during merging. I faced this problem while combining old phone backups with new cloud exports and lost several contacts using free tools. After switching to WholeClear Merge vCard Software, everything merged smoothly because it supports all vCard versions together. The software understood each format correctly and kept all contact details exactly as saved. No manual fixing was required, and even large contact lists merged without any errors.
