Post From: Vwap study incorrect following recent update

Symbol: BTCUSDT_PERP_BINANCE
Study: ECIVwapV1.5

First, this appears to be isolated to my Historical chart on BTCUSDT_PERP_BINANCE. I have multiple intraday charts running the same ECIVwapV1.5 study in the same BTCUSDT_PERP_BINANCE chartbook and all are working correctly. For reference, All of my other CME/NYMEX/COMEX historical charts are fine display the ECIVwap1.5 study correctly.

I have never had an issue displaying this chart/study before. Tonight I ran the recent update to take advantage of the recent fix to "The Z-Order of the windows also may not have been restored correctly when reopening a Chartbook or switching between loaded Chartbooks"--- big thank you for fixing this. I attempted months ago to explain this issue, but I think I was unsuccessful in getting my point across- it was tough to explain.

Back to my ECIVwap issue. Following the update tonight, my Historical Chart with Yearly ECIVwap is skewed and unusable and I have included a screenshot. I have double checked all settings associated with crypto charts- Auto set from data feed to NO. I have tried "Delete Data and Download" and this does not work. I tried rebuilding the chart from scratch, but this does not fix the issue.

I was able to add the standard Volume Weighted Average Price study to a historical BTCUSDT_PERP_BINANCE chart successfully. But this standard Vwap study lacks the extension features that ECIVwapV1.5 offers and I require.

What can I do to fix my ECIVwapV1.5 study on my historical chart?

Thank you for all your help
