That's completely normal. If coins are staking too often (typically the threshold is 1 day), the inputs are considered to be too big, and are being automatically split by your wallet, so network could regularly produce the needed amount of blocks, and thus be more healthy.

This will not affect your staking amount in any way, you will just stake more often, but in smaller portions.

If the coin is coded correctly, you do not need to do anything, your inputs will split and combine automatically, to reflect the condition on the chain and current network staking weight.
