Gunbot xt 6 USDT_XXX issue, poloniex

[coinewb182]

So i've duplicated bb strategy just for USDT named it "bbUSD".
I've set trading limit to 500 for obvious reasons and started trading on 5 pairs on poloniex.
Curiously only one pair was active all day - it was USDT_XRP. Few buys and sells here and there.
Looking at coin charts it shouldnt be a case and also it would be extreme luck to have only one pair out of 5 traded and traded like P =1/5*1/5*1/5 and so on...

So i entered log to find if there are any differences and they are...

USDT_XRP
2017/11/16 16:36:18: Last Bid/Strategy Exit Point: 0.24410001/0.24393903
2017/11/16 16:36:18: Last Ask/Strategy Entry Point: 0.24453703/0.24492887
2017/11/16 16:36:18: There are some trading opportunities

USDT_ANY_OTHER_COIN
2017/11/16 22:44:27: Last Bid/Strategy Exit Point: 297.32137992/NaN
2017/11/16 22:44:27: Last Ask/Strategy Entry Point: 298.34275977/298.16972550
No new opportunities found...

Conclusion any other coin produces "NaN" value in "Last Bid/Strategy Exit Point" field.
Also i noticed XRP to USDT value is kinda 0.0ish just like what you'd expect for BTC_XXX trade.
Other coins like ZEC,DASH to USDT are 300ish or 400ish.
Maybe thats why only this USDT_XRP pair works somehow.

So, am I doing something wrong? Is this a known issue?
Btw i am a noob in this so don't be harsh.

By buying manually some small amounts of those "NaN" coins i was able to get rid of NaN values.
The only issue is, right after i did this, bot sold all my dash lol.
But after shutting down the bot and restarting it, NaN values dissapeared.
