All In One Divergence Indicator

Good day. I tried installing your "all-in-one-divergence-indicator" on your list of free indicators. I back tested it several times. I just modified the alerts section for notifications. At first it was great, but recently, it gives two signals on a one asset but with different direction opposing each other. Should I be modifying some of its settings? for example, on a 5 minute time frame on Eur/Usd, 2 signals were given on the same time. 1 signal says to buy then the other signal tells to sell. It happened several times. Can I ask for help.
Thank you
