It's not really a wallet issue. It's how Bitcoin transactions work by design. Every transaction creates a separate input in your wallet. When you send a transaction the wallet generally takes ALL the inputs, puts them into one output and sends that to the network. Now, if you have received a decent numbers of transactions each input adds to your tx bloat. Decent wallets (like Electrum) have a coin control option. The way that works is, you select a specific address in your wallet to send from. Then you open coin control and remove all inputs that aren't needed to meet the sum you want to send. Then you broadcast your transaction and it will be cheaper. In some cases A LOT cheaper.
