Superchart breaks when scrolling back in time

Hi colleagues, we have been using blink in chiller monitoring projects for more than a year, the charts worked great, recently discovered a problem - that when scrolling back in time, the chart “breaks” and does not display some datastreams. It is noted that the problem is observed only on datastreams that have interruptions in data transmission time and are interpolated (using connect missing data point).
Please tell me where it comes from and how to solve this problem?
