I think it is a false positive  I hope it will not cause you trouble.

Non-detection of 2026X

Follow-up imaging with the Las Cumbres Observatory from Cerro Tololo in r-band reveals no point-like emission.  We subtracted a Pan-STARRS 3pi r-band template and do not detect any transient emission to a 3-sigma limiting magnitude of >20.1 mag.  The attached image shows our follow-up image (left), a Pan-STARRS template (middle), and the difference image (right) centered at the position of the transient.
