A sample trace file of what you are seeing would be a big help. For example, it can be used to quickly rule out many basic things that may or may not be an issue - but no way to know for sure without looking.
Otherwise, can only provide general guidance as there are many things that could be affecting this - for example, looking for Data frames when QoS Data frames are in use; sniffing on the wrong channel; too far away; trying to capture with a USB adapter inside a VM; using the adapter at the same time in both managed and monitor mode; trying to capture high data-rate frames with a less-capable adapter; the list goes on.
