SHR has this issue. You can't add a drive smaller than the smallest drive in the current raid setup.
You could add the two 3TB drives as a new SHR pool/volume, move your data to that new volume.
Then delete the old two 4TB pool/volume.
Lastly, you can add two 4TB drives to the new SHR pool/volume, Giving you about 9TB
PLEASE NOTE: You may also get issues if you don't remove the apps first as the Synology uses Volume 1 as default, and when you make the new pool/volume you will make Volume 2 and this can have funny results with broken apps left installed when volume 1 is no longer there.
