Nothing to worry about, unless its causing some issues. 1GB RAM phones are like that, its normal.
There is power saving and background app management settings in Huawei. Go to protected apps list in power saving settings and only protect the most important and most necessary apps. In this way, non important apps will not run in background and you will get more free memory. Huawei phones have built in Greenify like system.
Follow what i say and get rid of any app claiming to improve RAM, performance and battery timings etc, they are all junk!.
